convert4aLFQ: Convert table into the format expected by aLFQ.

In peterblattmann/SWATH2stats: Transform and Filter SWATH Data for Statistical Packages

Convert table into the format expected by aLFQ.

Description

This function selects the columns necessary for the aLFQ R package.

Usage

convert4aLFQ(data, annotation = TRUE, check_transitions = TRUE)

Arguments

data	A data frame containing the SWATH data in transition-level format
annotation	Option to indicate if the data has been annotated, i.e. if the columns Condition, Replicate, Run are present. If option is set to true it will write a new run_id as a string of the combination of these three columns.
check_transitions	Option if number of transitions should be checked. As input only transition-level data should be used and therefore this is checked. However, this makes the function slow and herewith be omitted.

Value

Returns a data frame in the appropriate format for aLFQ.
