Enrichment Bar Plot with Two Directions

Description

Creates a bar plot visualizing enrichment results for up-regulated and down-regulated terms, using -log10(p-values) to indicate significance.

Usage

enrichment_barplot(
  up_terms,
  down_terms,
  terms = "Description",
  pvalue = "pvalue",
  group = "group",
  palette = "jama",
  cols = NULL,
  title = "Gene Ontology Enrichment",
  width_wrap = 30,
  font_terms = 15
)

Arguments

up_terms	Data frame for up-regulated terms.
down_terms	Data frame for down-regulated terms.
terms	Column name for term descriptions. Default is "Description".
pvalue	Column name for p-values. Default is "pvalue".
group	Column name for group indicator. Default is "group".
palette	Color palette. Default is "jama".
cols	Character vector. Custom colors for bars. If NULL, uses palette. Default is NULL.
title	Plot title. Default is "Gene Ontology Enrichment".
width_wrap	Maximum width for wrapping pathway names. Default is 30.
font_terms	Font size for axis labels. Default is 15.

Value

A ggplot object of the enrichment bar plot.
