## assess_decoy_rate: Assess decoy rate

### Description

This function counts the number of decoy peptides.

### Usage

    assess_decoy_rate(data)

### Arguments

`data` | A data frame that contains at least a column named "FullPeptideName" and "decoy".

### Details

A printout is generated to indicate the number of non-decoy, decoy peptides and the rate of decoy vs non-decoy peptides. Unique peptides are counted, so a precursor with different charge states is counted as one peptide. In the column "decoy" the values need to be 1,0 or TRUE and FALSE.

### Value

Prints the decoy rate.
