### Usage

    deg_def(diffexp, pcriteria, foldchangecol, pv, fc)

### Arguments

`diffexp` | data.frame/data.table with differential expression results
`pcriteria` | column name of the pvalue variable <strings>
`foldchangecol` | column name of the foldchange variable <string>
`pv` | pvalue threshold <double>
`fc` | foldchange threshold <double>

### Value

`data.table/data.frame` with a new deg variable

### Examples

    data(diffexplist)
    diffexp <- deg_def(diffexplist[[1]], "pvalue", "Log2FC", 0.05, 0)
    table(diffexp[['deg']])
