plot volcano

Description

plot volcano plot for DESeq2 pariwise compare result

Usage

plot_volcano(
  res,
  fc_thred = 2,
  padj_thred = 0.05,
  size = 1.5,
  alpha = 0.7,
  title = "Volcano of DEGs",
  xlim = NULL,
  ylim = NULL,
  ns_resampling = 1000,
  color = c("#0571b0", "#bababa", "#ca0020")
)

Arguments

res	a data.drame from DESeq2 result
fc_thred	foldchange cutoff, corelated to log2FoldChange column, high value mean less filter
padj_thred	p.adjust cutoff, corelated to padj column, high value mean less filter
size	point size
alpha	point transparency
title	plot title
xlim	two element numeric vector, restrict x axis, default: NULL
ylim	two element numeric vector, restrict y axis, default: NULL
ns_resampling	numeric, downsampling NS points
color	three element character vector, map point color, ordered by down-regulated, ns, up-regulated

Value

ggplot2 object
