- For cols: remove columns that are not neccessary any more

### Usage

    simplifyProteins(.data, direction = c("rows", "cols"))

### Arguments

`.data` | a dataframe
`direction` | character, rows, cols or both

### Value

a dataframe

### Examples

    ##Use example peptide data set, read in and clean data
    inputFile <- system.file("extData", "data.txt", package = "ComPrAn")
    peptides <- peptideImport(inputFile)
    peptides <- cleanData(peptides, fCol = "Search ID")
    ## separate chemical modifications and labelling into separate columns
    peptides <- splitModLab(peptides)
    ## remove unneccessary columns, simplify rows
