Make complex heatmaps

Description

Make complex heatmaps

Details

This package aims to provide a simple and flexible way to arrange multiple heatmaps as well as flexible annotation graphics.

The package is implemented in an object-oriented way. The heatmap lists are abstracted into several classes.

There are also several internal classes:

Following two high-level functions take use of functionality of complex heatmaps:

  • oncoPrint: oncoPrint plot which visualize genomic alterations in a set of genes.

  • densityHeatmap: use heatmaps to visualize density distributions.

The complete reference of ComplexHeatmap package is available at http://jokergoo.github.io/ComplexHeatmap-reference/book.

Subset an AnnotationFunction Object

Description

Subset an AnnotationFunction Object

Usage

## S3 method for class 'AnnotationFunction'
x[i]

Arguments

x

An AnnotationFunction-class object.

i

A vector of indices.

Details

One good thing for designing the AnnotationFunction-class is it can be subsetted, and this is the base for the splitting of the annotations.

Examples

anno = anno_simple(1:10)
anno[1:5]
draw(anno[1:5], test = "subset of column annotation")

Subset the Combination Matrix

Description

Subset the Combination Matrix

Usage

## S3 method for class 'comb_mat'
x[i, j, drop = FALSE]

Arguments

x

A combination matrix returned by make_comb_mat.

i

Indices on rows.

j

Indices on columns.

drop

It is always reset to FALSE internally.

Details

If sets are on rows of the combination matrix, the row indices correspond to sets and column indices correspond to combination sets, and if sets are on columns of the combination matrix, rows correspond to the combination sets.

If the index is one-dimension, e.g. x[i], the index always corresponds to the combination sets.

You should not subset by the sets. It will give you wrong combination set size. The subsetting on sets are only used internally.

This subsetting method is mainly for subsetting combination sets, i.e., users can first use comb_size to get the size of each combination set, and filter them by the size.

Examples

set.seed(123)
lt = list(a = sample(letters, 10),
          b = sample(letters, 15),
          c = sample(letters, 20))
m = make_comb_mat(lt)
m2 = m[, comb_size(m) >= 3]
comb_size(m2)
m[comb_size(m) >= 3]

Description

Subset a HeatmapList object

Usage

## S3 method for class 'HeatmapList'
x[i, j]

Arguments

x

A HeatmapList-class object

i

row indices

j

column indices

Details

If the heatmap list is horizontal, i is the row indices and j corresponds to heatmap names and single annotation names. and if the heatlist is vertical, i corresponds to heatmap/annotation names and j is the column indices.

Examples

ht_list = Heatmap(matrix(rnorm(100), 10), name = "rnorm") +
  rowAnnotation(foo = 1:10, bar = anno_points(10:1)) + 
  Heatmap(matrix(runif(100), 10), name = "runif")
summary(ht_list[1:5, ])
summary(ht_list[1:5, 1])
summary(ht_list[1:5, "rnorm"])
summary(ht_list[1:5, c("rnorm", "foo")])

ht_list = Heatmap(matrix(rnorm(100), 10), name = "rnorm") %v%
  columnAnnotation(foo = 1:10, bar = anno_points(10:1)) %v%
  Heatmap(matrix(runif(100), 10), name = "runif")
summary(ht_list[, 1:5])

Details

The SingleAnnotation class object is subsettable only if the containing AnnotationFunction-class object is subsettable. All the anno_* functions are subsettable, so if the SingleAnnotation object is constructed by one of these functions, it is also subsettable.

Examples

ha = SingleAnnotation(value = 1:10)
ha[1:5]
draw(ha[1:5], test = "ha[1:5]")

anno_empty(which = c("column", "row"), border = TRUE, zoom = FALSE,
    width = NULL, height = NULL, show_name = FALSE)

Arguments

which

Whether it is a column annotation or a row annotation?

border

Whether draw borders of the annotation region?

zoom

If it is true and when the heatmap is split, the empty annotation slices will have equal height or width, and you can see the correspondance between the annotation slices and the original heatmap slices.

width

Width of the annotation. The value should be an absolute unit. Width is not allowed to be set for column annotation.

height

Height of the annotation. The value should be an absolute unit. Height is not allowed to be set for row annotation.

show_name

Whether to show annotation name.

Details

It creates an empty annotation and holds space, later users can add graphics by decorate_annotation. This function is useful when users have difficulty to implement AnnotationFunction object.

In following example, an empty annotation is first created and later points are added:

	m = matrix(rnorm(100), 10)
	ht = Heatmap(m, top_annotation = HeatmapAnnotation(pt = anno_empty()))
	ht = draw(ht)
	co = column_order(ht)[[1]]
	pt_value = 1:10
	decorate_annotation("pt", {
		pushViewport(viewport(xscale = c(0.5, ncol(mat)+0.5), yscale = range(pt_value)))
		grid.points(seq_len(ncol(mat)), pt_value[co], pch = 16, default.units = "native")
		grid.yaxis()
		popViewport()
	})  

And it is similar as using anno_points:

	Heatmap(m, top_annotation = HeatmapAnnotation(pt = anno_points(pt_value)))  

Value

An annotation function which can be used in HeatmapAnnotation.

Constructor of AnnotationFunction Class

Description

Constructor of AnnotationFunction Class

Usage

AnnotationFunction(fun, fun_name = "", which = c("column", "row"), cell_fun = NULL,
    var_import = list(), n = NA, data_scale = c(0, 1), subset_rule = list(),
    subsettable = length(subset_rule) > 0, show_name = TRUE, width = NULL, height = NULL)

Arguments

fun

A function which defines how to draw the annotation. See **Details** section.

fun_name

The name of the function. It is only used for printing the object.

which

Whether it is drawn as a column annotation or a row annotation?

cell_fun

A simplified version of fun. cell_fun only accepts one single index and it draws repeatedly in each annotation cell.

var_import

The names of the variables or the variable themselves that the annotation function depends on. See **Details** section.

n

Number of observations in the annotation. It is not mandatory, but it is better to provide this information so that the higher order HeatmapAnnotation knows it and it can perform check on the consistency of annotations and heatmaps.

data_scale

The data scale on the data axis (y-axis for column annotation and x-axis for row annotation). It is only used when decorate_annotation is used with "native" unit coordinates.

subset_rule

The rule of subsetting variables in var_import. It should be set when users want the final object to be subsettable. See **Details** section.

subsettable

Whether the object is subsettable?

show_name

It is used to turn off the drawing of annotation names in HeatmapAnnotation. Annotations always have names associated and normally they will be drawn beside the annotation graphics to tell what the annotation is about. e.g. the annotation names put beside the points annotation graphics. However, for some of the annotations, the names are not necessarily to be drawn, such as text annotations drawn by anno_text or an empty annotation drawn by anno_empty. In this case, when show_names is set to FALSE, there will be no annotation names drawn for the annotation.

width

The width of the plotting region (the viewport) that the annotation is drawn. If it is a row annotation, the width must be an absolute unit. Since the AnnotationFunction object is always contained by the SingleAnnotation-classobject, you can only set the width of row annotations or height of column annotations, while e.g. the height of the row annotation is always unit(1, "npc") which means it always fully filled in the parent SingleAnnotation and only in SingleAnnotation or even HeatmapAnnotation can adjust the height of the row annotations.

height

The height of the plotting region (the viewport) that the annotation is drawn. If it is a column annotation, the width must be an absolute unit.

Details

In the package, we have implemted quite a lot annotation functions by AnnotationFunction constructor: anno_empty, anno_image, anno_points, anno_lines, anno_barplot, anno_boxplot, anno_histogram, anno_density, anno_joyplot, anno_horizon, anno_text and anno_mark. These built-in annotation functions support as both row annotations and column annotations and they are are all subsettable.

The build-in annotation functions are already enough for most of the analysis, nevertheless, if users want to know more about how to construct the AnnotationFunction class manually, they can refer to https://jokergoo.github.io/ComplexHeatmap-reference/book/heatmap-annotations.html#implement-new-annotation-functions.

Value

A AnnotationFunction-class object which can be used in HeatmapAnnotation.

Examples

x = 1:10
anno1 = AnnotationFunction(
    fun = function(index, k, n) {
        n = length(index)
        pushViewport(viewport(xscale = c(0.5, n + 0.5), yscale = c(0, 10)))
        grid.rect()
        grid.points(1:n, x[index], default.units = "native")
        if(k == 1) grid.yaxis()
        popViewport()
    },
    var_import = list(x = x),
    n = 10,
    subsettable = TRUE,
    height = unit(2, "cm")
)
m = rbind(1:10, 11:20)
Heatmap(m, top_annotation = HeatmapAnnotation(foo = anno1))
Heatmap(m, top_annotation = HeatmapAnnotation(foo = anno1), column_km = 2)

The AnnotationFunction Class

Description

The AnnotationFunction Class

Details

The heatmap annotation is basically graphics aligned to the heatmap columns or rows. There is no restriction for the graphic types, e.g. it can be heatmap-like annotation or points. Here the AnnotationFunction class is designed for creating complex and flexible annotation graphics. As the main part of the class, it uses a user-defined function to define the graphics. It also keeps information of the size of the plotting regions of the annotation. And most importantly, it allows subsetting to the annotation to draw a subset of the graphics, which is the base for the splitting of the annotations.

See AnnotationFunction constructor for details.

Draw the Legends

Description

Draw the Legends

Usage

## S4 method for signature 'Legends'
draw(object, x = unit(0.5, "npc"), y = unit(0.5, "npc"), just = "centre", test = FALSE)

Arguments

object

The grob object returned by Legend or packLegend.

x

The x position of the legends, measured in current viewport.

y

The y position of the legends, measured in current viewport.

just

Justification of the legends.

test

Only used for testing.

Details

In the legend grob, there should always be a viewport attached which is like a wrapper of all the graphic elements in a legend. If in the object, there is already a viewport attached, it will modify the x, y and valid.just of the viewport. If there is not viewport attached, a viewport with specified x, y and valid.just is created and attached.

You can also directly use grid.draw to draw the legend object, but you can only control the position of the legends by first creating a parent viewport and adjusting the position of the parent viewport.

Examples

lgd = Legend(at = 1:4, title = "foo")
draw(lgd, x = unit(0, "npc"), y = unit(0, "npc"), just = c("left", "bottom"))

# and a similar version of grid.draw
pushViewport(viewport(x = unit(0, "npc"), y = unit(0, "npc"), just = c("left", "bottom")))
grid.draw(lgd)

Draw the Dendrogram

Description

Draw the Dendrogram

Usage

grid.dendrogram(dend, ..., test = FALSE)

Arguments

dend

A dendrogram object.

...

Pass to dendrogramGrob.

test

Is it in test mode? If it is in test mode, a viewport is created by calculating proper xlim and ylim.

Details

grid.dendrogram supports drawing dendrograms with self-defind leaf positions. The positions of leaves can be defined by adjust_dend_by_x. Also the dendrogram can be customized by setting the edgePar attribute for each node (basically for controlling the style of segments), e.g. by color_branches.

To draw the dendrogram, a viewport should be firstly created. dend_xy can be used to get the positions of leaves and height of the dendrogram.

Examples

m = matrix(rnorm(100), 10)
dend = as.dendrogram(hclust(dist(m)))
grid.newpage()
pushViewport(viewport(xscale = c(0, 10.5), yscale = c(0, dend_heights(dend)), 
    width = 0.9, height = 0.9))
grid.dendrogram(dend)
popViewport()

grid.dendrogram(dend, test = TRUE)

require(dendextend)
dend = color_branches(dend, k = 2)
dend = adjust_dend_by_x(dend, unit(sort(runif(10)*10), "cm"))
grid.dendrogram(dend, test = TRUE)

Make a Combination Matrix for UpSet Plot

Description

Make a Combination Matrix for UpSet Plot

Usage

make_comb_mat(..., mode = c("distinct", "intersect", "union"),
    top_n_sets = Inf, min_set_size = -Inf,
    universal_set = NULL, complement_size = NULL,
    value_fun = NULL, set_on_rows = TRUE)

Arguments

...

The input sets. If it is represented as a single variable, it should be a matrix/data frame or a list. If it is multiple variables, it should be name-value pairs, see Input section for explanation.

mode

The mode for forming the combination set, see Mode section.

top_n_sets

Number of sets with largest size.

min_set_size

Ths minimal set size that is used for generating the combination matrix.

universal_set

The universal set. If it is set, the size of the complement set of all sets is also calculated. It if is specified, complement_size is ignored.

complement_size

The size for the complement of all sets. If it is specified, the combination set name will be like "00...".

value_fun

For each combination set, how to calculate the size? If it is a scalar set, the length of the vector is the size of the set, while if it is a region-based set, (i.e. GRanges or IRanges object), the sum of widths of regions in the set is calculated as the size of the set.

set_on_rows

Used internally.

Value

A matrix also in a class of comb_mat.

Following functions can be applied to it: set_name, comb_name, set_size, comb_size, comb_degree, extract_comb and t.comb_mat.

Input

To represent multiple sets, the variable can be represented as:

1. A list of sets where each set is a vector, e.g.:

    list(set1 = c("a", "b", "c"),
         set2 = c("b", "c", "d", "e"),
         ...)  

2. A binary matrix/data frame where rows are elements and columns are sets, e.g.:

      a b c
    h 1 1 1
    t 1 0 1
    j 1 0 0
    u 1 0 1
    w 1 0 0
    ...  

If the variable is a data frame, the binary columns (only contain 0 and 1) and the logical columns are only kept.

The set can be genomic regions, then it can only be represented as a list of GRanges objects.

Mode

E.g. for three sets (A, B, C), the UpSet approach splits the combination of selecting elements in the set or not in the set and calculates the sizes of the combination sets. For three sets, all possible combinations are:

    A B C
    1 1 1
    1 1 0
    1 0 1
    0 1 1
    1 0 0
    0 1 0
    0 0 1  

A value of 1 means to select that set and 0 means not to select that set. E.g., "1 1 0" means to select set A, B while not set C. Note there is no "0 0 0", because the background size is not of interest here. With the code of selecting and not selecting the sets, next we need to define how to calculate the size of that combination set. There are three modes:

1. distinct mode: 1 means in that set and 0 means not in that set, then "1 1 0" means a set of elements also in set A and B, while not in C (i.e. setdiff(intersect(A, B), C)). Under this mode, the seven combination sets are the seven partitions in the Venn diagram and they are mutually exclusive.

2. intersect mode: 1 means in that set and 0 is not taken into account, then, "1 1 0" means a set of elements in set A and B, and they can also in C or not in C (i.e. intersect(A, B)). Under this mode, the seven combination sets can overlap.

3. union mode: 1 means in that set and 0 is not taken into account. When there are multiple 1, the relationship is OR. Then, "1 1 0" means a set of elements in set A or B, and they can also in C or not in C (i.e. union(A, B)). Under this mode, the seven combination sets can overlap.

Examples

set.seed(123)
lt = list(a = sample(letters, 10),
          b = sample(letters, 15),
          c = sample(letters, 20))
m = make_comb_mat(lt)

mat = list_to_matrix(lt)
mat
m = make_comb_mat(mat)

## Not run: 
require(circlize)
require(GenomicRanges)
lt = lapply(1:4, function(i) generateRandomBed())
lt = lapply(lt, function(df) GRanges(seqnames = df[, 1], 
    ranges = IRanges(df[, 2], df[, 3])))
names(lt) = letters[1:4]
m = make_comb_mat(lt)

Overlap genomic signals to the genomic bins

Description

Overlap genomic signals to the genomic bins

Usage

normalize_genomic_signals_to_bins(gr, value, value_column = NULL, method = "weighted",
    empty_value = NA, window = GHEATMAP_ENV$chr_window)

Arguments

gr

A GRanges object.

value

The corresponding signals corresponding to gr.

value_column

If value is not set and the values are in the meta-columns in gr, you can specify the column indices for these value columns, better to use name indices.

method

One of "weighted", "w0" and "absolute". For the three different methods, please refer to https://bioconductor.org/packages/release/bioc/vignettes/EnrichedHeatmap/inst/doc/EnrichedHeatmap.html#toc_7 .

empty_value

The value for the bins where no signal is overlapped.

window

The genomic bins generated from bin_genome.

Details

The genomic bins should be generated by bin_genome in advance. The genomic bins are saved internally, so that multiple uses of bin_genome ensure they all return the matrices with the same rows.

It supports following values.

  • When neither value nor value_column is set, it simply overlap gr to the genomic bins and returns a one-column logical matrix which represents whether the current genomic bin overlaps to any signal.

  • When the signals are numeric, value can be a numeric vector or a matrix, or value_column can contain multiple columns. The function returns a numeric matrix where the values are properly averaged depending on what method was used.

  • When the signals are character, value can only be a vector or value_column can only contain one single column. The function returns a one-column character matrix.

Value

A matrix with the same row as the genomic bins.

Usage

pindex(m, i, j)

Arguments

m

A matrix or a 3-dimension array.

i

Row indices or the indices in the first dimension.

j

Column indicies or the indices in the second dimension.

Value

If m is a matrix, the value returned is a vector c(m[i1, j1], m[i2, j2], ...)'.

Usage

## S4 method for signature 'HeatmapAnnotation'
re_size(object,
    annotation_height = NULL,
    annotation_width = NULL,
    height = NULL,
    width = NULL,
    simple_anno_size = object@param$simple_anno_size,

Arguments

object

A HeatmapAnnotation-class object.

annotation_height

A vector of of annotation heights in unit class.

annotation_width

A vector of of annotation widths in unit class.

height

The height of the complete heatmap annotation.

width

The width of the complete heatmap annotation.

simple_anno_size

The size of one line of the simple annotation.

simple_anno_size_adjust

Whether adjust the size of the simple annotation?

Details

The function only adjust height for column annotations and width for row annotations.

The basic rules are (take height and annotation_height for example:

1. If annotation_height is set and all annotation_height are absolute units, height is ignored. 2. If annotation_height contains non-absolute units, height also need to be set and the non-absolute units should be set in a simple form such as 1:10 or unit(1, "null"). 3. simple_anno_size is only used when annotation_height is NULL. 4. If only height is set, non-simple annotation is adjusted while keeps simple anntation unchanged. 5. If only height is set and all annotations are simple annotations, all anntations are adjusted, and simple_anno_size is disabled. 6. If simple_anno_size_adjust is FALSE, the size of the simple annotations will not change.

Restore the index vector to index matrix in layer_fun

Description

Restore the index vector to index matrix in layer_fun

Usage

restore_matrix(j, i, x, y)

Arguments

j

Column indices directly from layer_fun.

i

Row indices directly from layer_fun.

x

Position on x-direction directly from layer_fun.

y

Position on y-direction directly from layer_fun.

Details

The values that are sent to layer_fun are all vectors (for the vectorization of the grid graphic functions), however, the heatmap slice where layer_fun is applied to, is still represented by a matrix, thus, it would be very convinient if all the arguments in layer_fun can be converted to the sub-matrix for the current slice. Here, as shown in above example, restore_matrix does the job. restore_matrix directly accepts the first four argument in layer_fun and returns an index matrix, where rows and columns correspond to the rows and columns in the current slice, from top to bottom and from left to right. The values in the matrix are the natural order of e.g. vector j in current slice.

For following code:

    Heatmap(small_mat, name = "mat", col = col_fun,
        row_km = 2, column_km = 2,
        layer_fun = function(j, i, x, y, w, h, fill) {
            ind_mat = restore_matrix(j, i, x, y)
            print(ind_mat)
        }
    )  

The first output which is for the top-left slice:

         [,1] [,2] [,3] [,4] [,5]
    [1,]    1    4    7   10   13
    [2,]    2    5    8   11   14
    [3,]    3    6    9   12   15  

As you see, this is a three-row and five-column index matrix where the first row corresponds to the top row in the slice. The values in the matrix correspond to the natural index (i.e. 1, 2, ...) in j, i, x, y, ... in layer_fun. Now, if we want to add values on the second column in the top-left slice, the code which is put inside layer_fun would look like:

    for(ind in ind_mat[, 2]) {
        grid.text(small_mat[i[ind], j[ind]], x[ind], y[ind], ...)
    }  

Examples

set.seed(123)
mat = matrix(rnorm(81), nr = 9)
Heatmap(mat, row_km = 2, column_km = 2,
    layer_fun = function(j, i, x, y, width, height, fill) {
       ind_mat = restore_matrix(j, i, x, y)
       print(ind_mat)
})

set.seed(123)
mat = matrix(round(rnorm(81), 2), nr = 9)
Heatmap(mat, row_km = 2, column_km = 2,
    layer_fun = function(j, i, x, y, width, height, fill) {
       ind_mat = restore_matrix(j, i, x, y)
       ind = unique(c(ind_mat[2, ], ind_mat[, 3]))
       grid.text(pindex(mat, i[ind], j[ind]), x[ind], y[ind])
})

Constructor Method for SingleAnnotation Class

Description

Constructor Method for SingleAnnotation Class

Usage

SingleAnnotation(name, value, col, fun,
    label = NULL,
    na_col = "grey",
    which = c("column", "row"),
    show_legend = TRUE,
    gp = gpar(col = NA),
    border = FALSE,
    legend_param = list(),
    show_name = TRUE,
    name_gp = gpar(fontsize = 12),
    name_offset = NULL,

    name_rot = NULL,
    simple_anno_size = ht_opt$simple_anno_size,
    width = NULL, height = NULL)

Arguments

name

Name for the annotation. If it is not specified, an internal name is assigned.

value

A vector or a matrix of discrete or continuous values.

col

Colors corresponding to value. If the mapping is discrete, the value of col should be a named vector; If the mapping is continuous, the value of col should be a color mapping function.

fun

A user-defined function to add annotation graphics. The argument of this function should be at least a vector of index that corresponds to rows or columns. Normally the function should be constructed by AnnotationFunction if you want the annotation supports splitting. See **Details** for more explanation.

label

Label for the annotation. By default is the annotation name.

na_col

Color for NA values in the simple annotations.

which

Whether the annotation is a row annotation or a column annotation?

show_legend

If it is a simple annotation, whether show legend in the final heatmap?

gp

Since simple annotation is represented as rows of grids. This argument controls graphic parameters for the simple annotation. The fill parameter is ignored here.

border

border, only work for simple annotation

legend_param

Parameters for the legend. See color_mapping_legend,ColorMapping-method for all possible options.

show_name

Whether show annotation name?

name_gp

Graphic parameters for annotation name.

name_offset

Offset to the annotation, a unit object.

name_side

'right' and 'left' for column annotations and 'top' and 'bottom' for row annotations

name_rot

Rotation of the annotation name.

simple_anno_size

size of the simple annotation.

width

The width of the plotting region (the viewport) that the annotation is drawn. If it is a row annotation, the width must be an absolute unit.

height

The height of the plotting region (the viewport) that the annotation is drawn. If it is a column annotation, the width must be an absolute unit.

Details

A single annotation is a basic unit of complex heatmap annotations where the heamtap annotations are always a list of single annotations. An annotation can be simply heatmap-like (here we call it simple annotation) or more complex like points, lines, boxes (for which we call it complex annotation).

In the SingleAnnotation constructor, value, col, na_col are used to construct a anno_simple annotation funciton which is generated internally by AnnotationFunction. The legend of the simple annotation can be automatcally generated,

For construcing a complex annotation, users need to use fun which is a user-defind function. Normally it is constucted by AnnotationFunction. One big advantage for using AnnotationFunction is the annotation function or the graphics drawn by the annotation function can be split according to row splitting or column splitting of the heatmap. Users can also provide a "pure" function which is a normal R function for the fun argument. The function only needs one argument which is a vector of index for rows or columns depending whether it is a row annotation or column annotation. The other two optional arguments are the current slice index and total number of slices. See **Examples** section for an example. If it is a normal R function, it will be constructed into the AnnotationFunction-class object internally.

The SingleAnnotation-class is a simple wrapper on top of AnnotationFunction-class only with annotation name added.

The class also stored the "extended area" relative to the area for the annotation graphics. The extended areas are those created by annotation names and axes.

Value

A SingleAnnotation-class object.

There are following built-in annotation functions that can be directly used to generate complex annotations: anno_simple, anno_points, anno_lines, anno_barplot, anno_histogram, anno_boxplot, anno_density, anno_text, anno_joyplot, anno_horizon, anno_image, anno_block, anno_summary and anno_mark.

Examples

ha = SingleAnnotation(value = 1:10)
draw(ha, test = "single column annotation")

m = cbind(1:10, 10:1)
colnames(m) = c("a", "b")
ha = SingleAnnotation(value = m)

anno = anno_barplot(matrix(nc = 2, c(1:10, 10:1)))
ha = SingleAnnotation(fun = anno)
draw(ha, test = "anno_barplot as input")

fun = local({
    # because there variables outside the function for use, we put it a local environment
    value = 1:10
    function(index, k = 1, n = 1) {
        pushViewport(viewport(xscale = c(0.5, length(index) + 0.5), yscale = range(value)))

Make the UpSet plot

Description

Make the UpSet plot

Usage

    set_order = order(set_size(m), decreasing = TRUE),
    comb_order = if(attr(m, "param")$set_on_rows) {
    order.comb_mat(m[set_order, ], decreasing = TRUE)
    } else {
    order.comb_mat(m[, set_order], decreasing = TRUE)
    },
    top_annotation = upset_top_annotation(m),
    right_annotation = upset_right_annotation(m),
    left_annotation = NULL,
    row_names_side = "left",
    ...)

Arguments

m

A combination matrix returned by make_comb_mat. The matrix can be transposed to switch the position of sets and combination sets.

comb_col

The color for the dots representing combination sets.

pt_size

The point size for the dots representing combination sets.

lwd

The line width for the combination sets.

bg_col

Color for the background rectangles.

bg_pt_col

Color for the dots representing the set is not selected.

set_order

The order of sets.

comb_order

The order of combination sets.

top_annotation

A HeatmapAnnotation object on top of the combination matrix.

left_annotation

A HeatmapAnnotation object on top of the combination matrix.

right_annotation

A HeatmapAnnotation object on the right of the combination matrix.

row_names_side

The side of row names.

...

Other arguments passed to Heatmap.

Details

By default, the sets are on rows and combination sets are on columns. The positions of the two types of sets can be switched by transposing the matrix.

When sets are on rows, the default top annotation is the barplot showing the size of each combination sets and the default right annotation is the barplot showing the size of the sets. The annotations are simply constructed by HeatmapAnnotation and anno_barplot with some parameters pre-set. Users can check the source code of upset_top_annotation and upset_right_annotation to find out how the annotations are defined.

To change or to add annotations, users just need to define a new HeatmapAnnotation object. E.g. if we want to change the side of the axis and name on top annotation:

    Upset(..., top_annotation = 
        HeatmapAnnotation(
           "Intersection size" = anno_barplot(
               comb_size(m), 
               border = FALSE, 
               gp = gpar(fill = "black"), 
               height = unit(2, "cm"),
               axis_param = list(side = "right")
           ), 
           annotation_name_side = "right", 
           annotation_name_rot = 0)
    )  

To add more annotations on top, users just add it in HeatmapAnnotation:

    Upset(..., top_annotation = 
        HeatmapAnnotation(
           "Intersection size" = anno_barplot(
               comb_size(m), 
               border = FALSE, 
               gp = gpar(fill = "black"), 
               height = unit(2, "cm"),
               axis_param = list(side = "right")
           ), 
           "anno1" = anno_points(...),
           "anno2" = some_vector, 
           annotation_name_side = "right", 
           annotation_name_rot = 0)
    )  

And so is for the right annotations.

UpSet returns a Heatmap-class object, which means, you can add it with other heatmaps and annotations by + or %v%.

Examples

set.seed(123)
lt = list(a = sample(letters, 10),
