In vladpetyuk/vp.misc: Miscellaneous functions used by Vlad Petyuk for proteomics data analysis

Description

A primary purpose of this function is to roll-up peptide measurements to protein level. Ultimately it can be used for rolling-up or combining any features according to a grouping factor.

Usage

rrollup(msnset, rollBy, rollFun, verbose = TRUE)

Arguments

msnset	msnset (or most likely eset subclass) object
rollBy	character. A column name in pData(msnset)
rollFun	function for roll-up. "-" for log-transformed data, "/" for normal scale
verbose	logical. Controls real-time output.

Value

MSnSet object

Examples

data(srm_msnset)
dim(msnset)
msnset2 <- rrollup(msnset, rollBy="Gene", rollFun="-", verbose=TRUE)
dim(msnset2)
