Similarly to plotGeneralEnrichment and plotTFEnrichment, the results of the community-based enrichment analysis are plotted. This function produces multiple plots. First, one plot per community to summarize the community-specific enrichment. Second, a summary heatmap of all significantly enriched terms across all communities and for the whole eGRN. The latter allows to compare the results with the general network enrichment. Third, a subset of the aforementioned heatmap, showing only the top most significantly enriched terms per community and for the whole eGRN (as specified by nID) for improved visibility

Object of class GRN


Character or NULL. Default NULL. If set to NULL, the default output folder as specified when initiating the object in initializeGRN will be used. Otherwise, all output from this function will be put into the specified folder. If a folder is provided, while we recommend specifying an absolute path, a relative one also works.


NULL or character. Default NULL. Basename of the output files that are produced. If set to NULL, a default basename is chosen. If a custom basename is specified, all output files will have the chosen basename as file prefix, be careful with not overwriting already existing files (if forceRerun is set to TRUE)


Character. Default "byRank". One of: "byRank", "byLabel". Specify whether the communities will be selected based on their rank or explicitly by their label. Note that the label is independent of the rank. When set to "byRank", the largest community (with most vertices) always has a rank of 1.


NULL or numeric vector or character vector. Default NULL. If set to NULL, all community enrichments that have been calculated before are plotted. If a numeric vector is specified (when selection = "byRank"), the rank of the communities is specified. For example, communities = c(1,4) then denotes the first and fourth largest community. If a character vector is specified (when selection = "byLabel"), the name of the communities is specified instead. For example, communities = c("1","4") then denotes the communities with the names "1" and "4", which may or may not be the largest and fourth largest communities among all.


Numeric. Default 30. Maximum number of ontology terms that meet the p-value significance threshold to display in the enrichment dot plot


Numeric. Default 0.05. p-value threshold to determine significance.


Numeric > 0. Default 3. Threshold to filter out an ontology term with less than nSignificant overlapping genes.


Numeric > 0. Default 10. For the reduced summary heatmap, number of top terms to select per community / for the general enrichment.


Integer (>=10). Default 50. Maximum number of characters for a term before it is truncated.


TRUE or FALSE. Default FALSE. Is the p-value being displayed in the plots the adjusted p-value? This parameter is relevant for KEGG, Disease Ontology, and Reactome enrichments, and does not affect GO enrichments.


TRUE or FALSE. Default TRUE.Should the plots be printed to a PDF file? If set to TRUE, a PDF file is generated, the name of which depends on the value of basenameOutput. If set to FALSE, all plots are printed to the currently active device. Note that most functions print more than one plot, which means you may only see the last plot depending on your active graphics device.


Number>0. Default 12. Width of the PDF, in cm.


Number >0. Default 12. Height of the PDF, in cm.


Integer vector or NULL. Default NULL. Page number(s) to plot. Can be used to plot only specific pages to a PDF or the currently active graphics device.


TRUE or FALSE. Default FALSE. Force execution, even if the GRN object already contains the result. Overwrites the old results.


The same GRN object, without modifications.
