plotVolcano: Volcano plot

In mariavica/mircomb: An R package for analyzing miRNA-mRNA interactions

Description

Volcano plot of miRNA or mRNA differential expression analysis

Usage

plotVolcano(obj, subset, FC1 = 1.5, FC2 = 2, FDR = 0.05, cex = 1,
   cex.lab = 1, cex.axis = 1 )

Arguments

obj	a "corObject" with a "diffexp.miRNA" or "diffexp.mRNA" slot already defined
subset	"miRNA" or "mRNA"
FC1	first FoldChange cutoff
FC2	second FoldChange cutoff
FDR	significance cutoff (FDR)
cex	cex value for the dots. Default is 1
cex.lab	cex of the label axis. Default is 1
cex.axis	cex of the axis. Default is 1

Value

A volcano plot of the miRNA or mRNA data from differential expression analysis. Items with FDR lower than the limit are highlighted in yellow. Items with FDR lower than the limit and higher than FC1 are highlighted in orange. Items with FDR lower than the limit and higher than FC2 are highlighted in red.
