aggregatePeptides: aggregate peptides

In wolski/imsbInfer: Visualization, normalization and QC of proteomics SWATH-MS data

Description

Given msexperiment with transitons aggregate the transitions to produce precursor intensities

Usage

aggregatePeptides(msexp, FUN = sum)

Arguments

msexp	msexperiment object
FUN	aggregation function

Examples

data(feature_alignment_requant)
colnames(feature_alignment_requant)
dim(feature_alignment_requant)/3
msexp = loadTransitonsMSExperiment( feature_alignment_requant , nrt = 3 , peptop = 3 )
dim(msexp)
sum(rownames(msexp$Intensity) == rownames(msexp$pepinfo))
y = aggregatePeptides(msexp)
sum(rownames(y$Intensity) == rownames(y$pepinfo))
dim(y)
stopifnot(table(table(y$pepinfo$transition_group_id)) == 247)
