The input for this function are tables obtained after running the Python import script.

### Usage

    getMATfromDataFrame(df, ID = "name")

### Arguments

`df` | the input data frame with positions in the columns and the genomic features in the rows.
`ID` | the name of the ID column to be removed.

### Value

a matrix with the ID column removed

### Examples

    data(exampleSampleTable)
    directory <- file.path(system.file("extdata", package="DChIPRep"))
    df  <- lapply(file.path(directory, exampleSampleTable$Input),
    read.delim)[[1]]
    mat <- getMATfromDataFrame(df)
