plyxp Usage Guide

Quick start

plyxp provides efficient abstractions to the SummarizedExperiment such that using common dplyr functions feels as natural to operating on a data.frame or tibble. plyxp uses data-masking from the rlang package in order to connect dplyr functions to SummarizedExperiment slots in a manner that aims to be intuitive and avoiding ambiguity in outcomes.

Supported data types and operations

plyxp works on SummarizedExperiment objects, as well as most classes derived from this, including DESeqDataSet, SingleCellExperiment, etc.

It supports the following operations:

  • mutate
  • select
  • summarize
  • pull
  • filter
  • arrange

Typical use case

library(airway)
data(airway)
library(dplyr)
library(plyxp)
# to use plyxp, call `new_plyxp()` on your SummarizedExperiment object
airway <- new_plyxp(airway)
# add data (mutate) to any of the three tables,
# assay, colData, rowData,
# ...using contextual helpers cols() and rows()
airway |>
  mutate(log_counts = log1p(counts),
         cols(treated = dex == "trt"),
         rows(new_id = paste0("gene-", gene_name)))

The operations can span contexts, and only the necessary data will be extracted from each context for computation:

airway$sizeFactor <- runif(8, .9, 1.1)

  mutate(scaled_counts = counts / .cols$sizeFactor, #

Calling .cols in the assay context produces an object of the matching size and orientation to the other assay data.

Alternatively we could have used purrr to compute row means:

airway |>
  mutate(scaled_counts = counts / .cols$sizeFactor,
         # You may expect a list when accessing other contexts
         # from either the rows() or cols() contexts.
         rows(ave_scl_cts = purrr::map_dbl(.assays$scaled_counts, mean)))

plyxp also enables common grouping and summarization routines:

summary <- airway |>
  group_by(rows(gene_biotype)) |>
  summarize(col_sums = colSums(counts),
            # may rename rows with .features
            rows(.features = unique(gene_biotype)))
# summarize returns a SummarizedExperiment here,
# retaining rowData and colData

Manipulating SummarizedExperiment with plyxp

The SummarizedExperiment object contains three main components/“contexts” that we mask, the assays(), rowData()1 and colData().

plyxp provides variables as-is to data within their current contexts enabling you to call S4 methods on S4 objects with dplyr verbs. If you require access to variables outside the context, you may use pronouns made available through plyxp to specify where to find those variables.

Simplified view of reshaping pronouns. Arrows indicates to where the pronoun provides access. For each pronoun listed, there is an _asis variant that returns underlying data without reshaping it to fit the context. Figure made with Biorender

The .assays, .rows and .cols pronouns outputs depends on the evaluating context. Users should expect that the underlying data returned from .rows or .cols pronouns in the assays context is a vector, replicated to match size of the assay context.


Alternatively, using a pronoun in either the rows() or cols() contexts will return a list equal in length to either nrows(rowData()) or nrows(colData()) respectively.

assay context

  • Default evaluation context
  • .assays → contextual pronoun, returns list of the matrix, sliced by the dimension it was referenced from.
    • within the rowData context: .assays$foo is an alias for lapply(seq_len(nrow()), \(i, x) x[i,,drop=FALSE], x = foo)
    • within the colData context: .assays$foo is an alias for lapply(seq_len(ncol()), \(i, x) x[,i,drop=FALSE], x = foo)
  • .assays_asis → pronoun to direct bindings in assays()
  • assay_ctx(expr, asis = FALSE) → short hand to bind the assay context in front of the current context.

rows context

  • rows(...) → sentinel function call to indicate evaluation context.
  • .rows → contextual pronoun
    • within assay context: .rows$foo is an alias for vctrs::vec_rep(foo, times = ncol())
    • within colData context: .rows$foo is an alias for vctrs::vec_rep(list(foo), times = n())
  • .rows_asis → pronoun to direct bindings in rowData()
  • row_ctx(expr, asis = FALSE) → shorthand to bind the rowData context in front of the current context

cols context

  • cols(...) → sentinel function call to indicate evaluation context.
  • .cols → contextual pronoun
    • within assay context: .cols$foo is an alias for vctrs::vec_rep_each(foo, times = nrow())
    • within rowData context: .rows$foo is an alias for vctrs::vec_rep(list(foo), times = n())
  • .cols_asis → pronoun to direct bindings in colData()
  • col_ctx(expr, asis = FALSE) → shorthand to bind the colData context in front of the current context

Multiple expressions enabled via plyxp

We can compare two ways of dividing out a vector from colData along the columns of assay data:

Advanced features

Object integrity

plyxp provides an opinionated framework for how dplyr verbs should interact with SummarizedExperiment objects. In general, plyxp will not allow any operations that it could not guarantee a valid return object.

It is for this reason that arrange(), filter() and group_by() do not allow operations in the default assay context, as this would likely break the assumed structure of a SummarizedExperiment object.

group_by()

plyxp also supports group_by operations allowing users to query information with dplyr::n() or dplyr::cur_group_id(). However due to the linked structure of a SummarizedExperiment object and plyxp providing multiple evaluation contexts, grouping operations would be complex and return values would be potentionally ambiguous.

It is for this reason that groupings are themselves contextual. The assay context is dependently linked to both the groupings of the rows and cols contexts but, the grouping of rows is ignored when viewed from the cols context and similarly the grouping of cols is ignored when viewed from the rows context. In this way, we have chosen to make the groupings of rows and cols independent between each other. The below figure attempts to show how groupings are conditionally dropped for the scope of an evaluation.

When evaluating in row context, groupings along colData() are temporarily ignored. Figure created with Biorender
When evaluating in row context, groupings along colData() are temporarily ignored. Figure created with Biorender

To further motivate this choice, suppose we did not drop grouping values. Assume you have a small 5 by 4 SummarizedExperiment object. Both of the rowData() and colData() are grouped such that there are 2 groups in both rowData() and colData() totaling in 4 groups across the assays.

group_by(se_simple, rows(direction), cols(condition)) |>
  mutate(rows(data_from_cols = .cols$condition))

The above syntax implies we wish to move data from the colData() into the rowData(). From a previously established conventions, we would expect the output to be an alias for vctrs::vec_rep(list(condition), times = n()).
Additionally the rows() sentinal will expect that the output of .cols$condition will need to match the size of the evaluation context.

Unfortunately, this becomes extremely difficult to resolve with the current conventions. Without dropping the cols() groupings, each rows() grouping is evaluated equal to the number of groups in cols(). At first glance, this may seem desirable, but the problem arises when considering how theses outputs across groups should be stored per group of rows(). For example, should the output of the .cols$condition return a list equal to the number of groups of the column context? If yes, we would need to consider the size stability of the output context! Assuming that rowData() has at least one group with three elements, there is no guarentee it would fit (this also makes a poor assumption that the elements of rowData() somehow correspond to the groups of colData()). Thus we would be left with wrapping all the results in a list and replicating to the appropriate size. When its all said and done, we would have a list of lists, which is difficult to reason about, potentionally unexpected and painful to work with. For this reason the only groupings present in the rowData() context are the groupings in rowData(), and similarly for the colData() context.

Printing

Motivated by the show/print function in tidySummarizedExperiment, we visualize the data as if it was tabular. plyxp offers the option to opt-in on this behavior by setting the associated global option:

options("show_SummarizedExperiment_as_tibble_abstraction" = TRUE)

Alternatively, you may use helper functions use_show_tidy() and use_show_default() to enable and disable this alternative printing respectively.

Since plyxp aims to leave the input data as-is when possible, we have considered providing support for printing S4Vectors within a tibble(). To be clear, plyxp will not allow you to put S4Vectors inside a tibble(), but will allow for S4Vectors to be printed with pillar(), the formatting engine behind tibble() pretty printing.

To enable this behavior, before any data is reported to the user, we proxy any S4Vector with a custom vctrs_vctr object with plyxp::vec_phantom(). In truth, the vec_phantom object is a simple integer vector with a “phantomData” attribute. This allows us to carry along S4Vector through pillar()’s printing pipeline until it is time to print the column.

The pillar_shaft() method for vec_phantom will format the S4 data with plyxp_pillar_format() generic, which by default calls S4Vectors::showAsCell(). Users are free to create their own methods for S4 vectors that differ from S4Vectors::showAsCell() if they like, as seen in ?`plyxp-printing`

renaming rows or columns

Inspired by tidySummarizedExperiment, plyxp provides access to the rownames and colnames of a SummarizedExperiment object by installing .features and .samples into the rowData() and colData() contexts respectively. These are special in that assigning a value to .features in the rowData() context or .samples in the colData() context does not create a new column, but changes the rownames or colnames of the resulting object.

Troubleshooting and best practices

while plyxp takes inspiration from the data masks used in dplyr, they are unfortunately more complex. This means there is some overhead in creating the evaluation mask per dplyr verb. Try to reduce the number of dplyr verb calls and instead increase the content of each verb. For example instead of doing:

.data |>
  mutate(foo = bar) |>
  mutate(baz = foo^2)

do the following

.data |>
  mutate(
    foo = bar,
    baz = foo^2
  )
