Dups: Average duplicated peptides from a VDAP dataset

In VDAP: Peptide Array Analysis Tools

Description

Looks for duplicate peptides in the first column of the dataset, averages the signal of duplicates and replaces them with a single row. A subfunction of vFormat

Usage

Dups(x)

Arguments

x	An R object, generally a data.frame with peptides in column 1, followed by signal values at various concentrations.

Value

Returns a data.frame without duplicated peptides. Duplicate entries display the mean of the signal at each concentration

Note

Duplicated peptide entries will generally be at the top of the dataset
