Plot enrichment results using -log10(FDR)

Generates a dot plot of enrichment results for enrichResult, gseaResult, or compareClusterResult objects (including those returned by enrichMsigDB()). Points are sized by gene/set count and coloured by -log10(FDR). For compareCluster results, the plot is faceted by cluster with top terms selected per cluster.

Usage

get_enrichment_plot(x, top_n = 10, title = NULL)

Arguments

x

An object of class enrichResult, gseaResult, or compareClusterResult.

top_n

Integer; number of top terms to plot (per cluster for compareCluster).

title

Optional plot title.

Value

A ggplot2 object.

Examples

if (FALSE) { # \dontrun{
v <- example_vista()
com <- names(comparisons(v))[1]
if (requireNamespace('msigdbr', quietly = TRUE)) {
  ms <- try(get_msigdb_enrichment(v, sample_comparison = com, regulation = 'Up', from_type = 'ENSEMBL'), silent = TRUE)
  if (!inherits(ms, 'try-error') && !is.null(ms$enrich)) print(get_enrichment_plot(ms$enrich))
}
} # }
