plot_enrichment_results: plot_enrichment_results

In XINA: Multiplexes Isobaric Mass Tagged-based Kinetics Data for Network Analysis

Description

Plot GO and KEGG enrichment results

Usage

plot_enrichment_results(enriched_results,
  term_description = "term_description", sig_score = "pvalue",
  num_terms = 0, get_log = TRUE, fill_color = "darkgray")

Arguments

enriched_results	GO or KEGG enrichment results. See xina_enrichment and xina_enrichment
term_description	Description of terms to be drawn on Y axis. Default is "term_description" of XINA enrichment results.
sig_score	significant score to plot on X axis. Default is "pvalue".
num_terms	The number of terms to be plotted. Default is 0, which menas no limit.
get_log	If this is TRUE, 'plot_enrichment_results' will take -log10 of p-values.
fill_color	Default is 'darkgray'. You can change color of bars.

Value

ggplot bar graph

# Enrichment test and get significantly enriched functional terms
# that have adjuseted p-value less than 0.1
