Peptide-level: Quantitative precision

get_CV_LFQ_pep.Rd

Calculate quantitative precision on peptide-level

Usage

get_CV_LFQ_pep(input_list)

Arguments

input_list

A list with data frames and respective quantitative peptide information.

Value

This function returns the original submitted data of the input_list including a new output column:

  • CV_Peptide_LFQ_mpwR - coefficient of variation in percentage.

Details

For each submitted data the coefficient of variation is calculated on peptide-level for LFQ intensities. Only full profiles are included.
