Methods for Function `breakEdges` in Package categoryCompare

Description

Methods for function breakEdges in package categoryCompare

Methods

signature(cwObject = "ccCompareResult", cutoff = "numeric"): Allows one to remove edges in the ccCompareResult mainGraph slot prior to passing it into Cytoscape for visualization. Given that the number of edges can be rather large (especially for Gene Ontology) this can easily speed up the transfer, without actually losing any information.
signature(cwObject = "numeric", cutoff = "numeric"): Once an annotation graph is in Cytoscape, remove edges above or below the cutoff. Note that this does not affect the original graph in the ccCompareResult object.

Author(s)

Robert M Flight

Examples

data(ccData)

# breaking the edges in a ccCompareResult
ccResults$BP <- breakEdges(ccResults$BP, 0.8)
## Not run: 
hasCy <- (if (.Platform$OS.type %in% "windows") {
(length(grep("Cytoscape", system("tasklist", intern=TRUE))) > 0)})

if hasCy {

	cwObj <- ccOutCyt(ccResults$BP,ccOpts)
	# now breaking them in the CytoscapeWindow object
	breakEdges(cwObj, 0.85)
	Sys.sleep(10)
	RCy3::deleteWindow(cwObj)
	}

## End(Not run)data(ccData)

# breaking the edges in a ccCompareResult
ccResults$BP <- breakEdges(ccResults$BP, 0.8)
## Not run: 
hasCy <- (if (.Platform$OS.type %in% "windows") {
(length(grep("Cytoscape", system("tasklist", intern=TRUE))) > 0)})

if hasCy {

	cwObj <- ccOutCyt(ccResults$BP,ccOpts)
	# now breaking them in the CytoscapeWindow object
	breakEdges(cwObj, 0.85)
	Sys.sleep(10)
	RCy3::deleteWindow(cwObj)
	}

Comparison of enriched annotations

Description

Takes the results from ccEnrich and compares the enriched annotations based on the settings previously set in ccOptions. Returns a ccCompareResult or ccCompareCollection object, see Details.

Usage

ccCompare(ccEnrichResult, ccOptions)

ccCompare(ccEnrichResult, ccOptions)

Arguments

`ccEnrichResult`	The enriched annotations collection returned from `ccEnrich`. This can be the `ccEnrichCollection`, `GOccEnrichResult`, or `KEGGccEnrichResult`
`ccOptions`	A `ccOptions` object that will determine which lists to actually compare against each other. See details below.

Details

Based on the enrichments found for each gene list, we now want to compare the annotations between lists. ccCompare accesses the annotations for each enrichment performed for each list, and makes the comparisons defined in ccOptions.

Value

ccCompare generates both a graph of the comparisons (to show how the categories are linked to each list and each other) and tabular output. The tabular output is a data frame, with ID for each term that was considered as a candidate annotation for each list, as well as a long description (Desc) of what the term is, and then membership and statistics from each gene list.

For each type of comparison (GO, KEGG, etc) a ccCompareResult is generated, with the following slots:

`mainGraph`	Annotations arranged as a graph
`mainTable`	The tabular results from all enrichment calculations combined into one
`allAnnotation`	A list of lists, where each entry is the annotation identifier, then a list for each comparison, with the genes that are annotated to that term that also belong to each list

The default is to generate an overlap graph for GO and KEGG, where the overlap is a measure of the similarity of the features (genes) annotated to each annotation term (based on a formula from EnrichmentMap). Optionally for GO, one can generate a hierarchical layout where the parent GO terms of the significant terms will also be included in the graph, with term origin saved in the node annotation (see example below to do this).

Only those terms with more than 10 and less than 500 annotated genes (according to the GO annotation file) are included.

When using weighted overlap graphs and RCy3 for viewing, it is recommended to use breakEdges and minNodes to remove edges with low weights and nodes with only a few genes from the dataset annotated to them.

Perform annotation enrichment for multiple gene lists

Description

Takes a ccGeneList object containing all the information needed to perform enrichment calculations for Gene Ontology.

Usage

ccEnrich(ccGeneList)
ccEnrich(ccGeneList)

Arguments

ccGeneList

A ccGeneList object, which is really just a list of lists, with some extra slots to tell us how to examine results. Each entry in the list should be named to allow identification later on. Each sub list should contain a vector genes denoting the genes of interest, a vector universe denoting the gene background (i.e. all genes on the chip), and an entry annotation denoting an organism database package (such as org.Hs.eg.db). See ccGeneList for more details regarding this object.

Details

This function is essentially a wrapper for hyperGTestCC that performs all of the calculations for the many gene lists in one go, returning a list of HyperGResultCC objects, one for each of the ccTypes and each gene list. These various HyperGResultCC objects can then be accessed and results compared among the lists for each of the ontologies

Value

A list of HyperGResultCC objects, one for each ccType and gene list, returned as ccEnrichResult objects for each ccType. This can be passed with a ccOptions object to ccCompare to generate actual annotation comparisons.

Class "ccGeneList"

Description

This stores the actual gene lists and related information that will be used in categoryCompare.

Objects from the Class

Objects can be created by calls of the form new("ccGeneList", list)). ccGeneList is actually just an extension of R list objects. The input list should be a list of lists. See Details for more information.

Slots

fdr:: Object of class "numeric" The number of fdr runs to perform to account for different list sizes and term dependence
pvalueCutoff:: Object of class "numeric" Value used to determine whether or not a particular term is significant or not
ccType:: Object of class "character" What types of annotations to use. Currently supported ones include "BP", "MF", "CC" (from Gene Ontology) and "KEGG"
testDirection:: Object of class "character" Are you interested in "over" or "under" represented annotations

Methods

fdr: signature(object = "ccGeneList"): how many random runs to perform
fdr<-: signature(object = "ccGeneList"): change the number of random runs
pvalueCutoff: signature(object = "ccGeneList"): what is the pvalue to consider significant
pvalueCutoff<-: signature(object = "ccGeneList"): change the cutoff for significance
ccType: signature(object = "ccGeneList"): what type of annotations are going to be examined
ccType<-: signature(object = "ccGeneList"): change the type of annotations to examine
testDirection: signature(object = "ccGeneList"): query for "over" or "under" represented annotations
testDirection<-: signature(object = "ccGeneList"): change the type of representation ("over" or "under")
listNames: signature(object = "ccGeneList"): what are the names of the lists contained

Details

The input list should be a list of lists, with at least three sub-lists.

testList <- list(list1=list(genes='...',universe='...',annotation='...'), list2=list(...))

genes: : These are the gene identifiers of the genes that are of interest (differentially expressed genes)
universe: : All of the genes that were measured in this particular experiments (i.e. all the genes on the chip)
annotation: : What organism or chip do these ID's come from (e.g. "org.Hs.eg.db" for Human Entrez gene ID's, "hgu133a.db" for probe ID's from the Affymetrix U133A chip)
data: : A data-frame that contains extra information about the genes of interest. At the very least, the data-frame must have a column ID that matches the ID's contained in genes

What actually happens when running ccEnrich is that the appropriate HyperGParamsCC objects are generated for each geneList and each type of annotation (e.g. BP, CC, KEGG), and then the calculations performed on each one.

Note

The ccGeneList object is what will undergo all of the enrichment calculations. When the results are combined with the ccOptions object, we can get our results of actual comparisons between experiments.

Class "ccOptions"

Description

These objects store the various options required by categoryCompare for actually making comparisons and generating output.

Objects from the Class

Objects can be created by calls of the form new("ccOptions", listNames=c('list1','list2',etc)). This is the minimum call required, and will generate a ccOptions object where comparisons are assumed between all the lists supplied. See the examples section for more examples of how to initialize new objects.

Slots

listNames:: Object of class "character" The actual names of the various datasets defined in the ccData object
compareNames:: Object of class "character" Which lists to compare, each entry should be a comma separated list
compareIndx:: Object of class "list" List indices for each of the comparison, not usually set by the user. Generated automatically.
compareColors:: Object of class "character" For graphical and tabular output each comparison can be colored. Should be one color for each comparison. Can be either an n by 3 matrix of rgb triples, or a character vector of hexadecimal color codes, or character vector of color names ('red','green','blue', etc)
cssClass:: Object of class "character" Classnames used when generating HTML tables to color entries. Generated automatically upon initialization, or modifying compareNames
outType:: Object of class "character" Sets the type of output generated by ccTables. Valid types are "html", "text", "rcy3" or "none", default is "text" when the ccOptions object is initialized without an outType specified.

Methods

compareColors: signature(object = "ccOptions"): ...

Methods for Function `ccOutCyt` in Package categoryCompare

Description

Passes a ccCompareResult object to Cytoscape for interactive visualization of ccCompare results.

Details

Note that only some basic, required methods have been imported from RCy3 for use with categoryCompare, and these are hidden in the functions within categoryCompare and are not visible to the user. If access to all the functionality of RCytoscape is desired (and trust me, there is a lot of useful stuff in there), then the user should use library(RCy3) directly.

It should also be noted that deletion of edges via RCy3 is slow, so some edge filtering should be done by breakEdges prior to using ccOutCyt.

Methods

signature(ccCompRes = "ccCompareResult", ccOpts = "ccOptions", ...): At a minimum, this method requires a ccCompareResult and a ccOptions to work.

... may include:

layout = "character": to override the default layout set by ccCompare, as well as options
postText = "character": to add a user set string to the Cytoscape window

In addition, any of the arguments to CytoscapeWindow may also be set, such as host or port.

Examples

## Not run: 
hasCy <- (if (.Platform$OS.type %in% "windows") {
(length(grep("Cytoscape", system("tasklist", intern=TRUE))) > 0)})

if hasCy {

	ccResults$BP <- breakEdges(ccResults$BP, 0.8)
	cwObj <- ccOutCyt(ccResults$BP,ccOpts)
	Sys.sleep(10)
	RCy3::deleteWindow(cwObj)
	}

## End(Not run)## Not run: 
hasCy <- (if (.Platform$OS.type %in% "windows") {
(length(grep("Cytoscape", system("tasklist", intern=TRUE))) > 0)})

if hasCy {

	ccResults$BP <- breakEdges(ccResults$BP, 0.8)
	cwObj <- ccOutCyt(ccResults$BP,ccOpts)
	Sys.sleep(10)
	RCy3::deleteWindow(cwObj)
	}
