### Description

Normalize the expression data of any type of experiment by columns, applying log(x + 1)/log(2).

### Usage

    normExp(tab)

### Arguments

`tab` | A matrix or dataframe of expression data (i.e. TPM, counts, FPKM).

### Value

Returns a table with normalized values.

### Examples

    # loading a simulated counts data
    data('simCounts')

    # getting the TPM matrix from counts
    tpm <- apply(simCounts, 2, function(x) {
                (1e+06 * x)/sum(x)
                })

    # normalizing TPM data
    norm <- normExp(tpm)
