## Volcano plot of differentially expressed genes/miRNAs

### Description

A volcano plot showing differentially expressed genes/miRNAs

### Usage

    gdcVolcanoPlot(deg.all, fc = 2, pval = 0.01)

### Arguments

`deg.all` | a dataframe generated from `gdcDEAnalysis` containing all genes of analysis no matter they are differentially expressed or not
`fc` | a numeric value specifying the threshold of fold change
`pval` | a nuemric value specifying the threshold of p value

### Value

A volcano plot
