Calculate all ratio pairs

Description

Calculations all possible ratios for the assayData columns in an "MSnSet".

Methods

signature(object = "MSnSet", log = "logical")

If log is FALSE (default) the ratios for all the assayData columns are computed; otherwise, log ratios (differences) are calculated.

Examples

library("pRolocdata")
data(dunkley2006)
x <- dunkley2006[, 1:3]
head(exprs(x))
r <- exprsToRatios(x)
head(exprs(r))
pData(r)
