In xjsun1221/bioinfor: Easier GEO analysis and plots

Description

print a volcano plot for Differential analysis result in data.frame fomat.

Usage

draw_volcano(deg, pvalue_cutoff = 0.05, logFC_cutoff = 1, pkg = 1,
  adjust = F)

Arguments

deg	a data.frame created by Differential analysis
pvalue_cutoff	Cutoff value of pvalue,0.05 by defult.
logFC_cutoff	Cutoff value of logFC,1 by defult.
pkg	a integer ,means which Differential analysis packages you used,we support three packages by now, 1,2,3,4 respectively means "DESeq2","edgeR","limma(voom)","limma"
adjust	a logical value, would you like to use adjusted pvalue to draw this plot,FAlSE by defult.

Value

a volcano plot according to logFC and P.value(or adjust P.value)
