Produce a scatterplot showing raw data point location in retention time and m/z. This plot is more useful for centroided data than continuum data.

Methods

object = "xcmsRaw"

plotRaw(object, mzrange = numeric(), rtrange = numeric(), scanrange = numeric(), log=FALSE, title='Raw Data')

Arguments

object

the xcmsRaw object

mzrange

numeric vector of length >= 2 whose range will be used to select the masses to plot

rtrange

numeric vector of length >= 2 whose range will be used to select the retention times to plot

scanrange

numeric vector of length >= 2 whose range will be used to select scans to plot

log

logical, log transform intensity

title

main title of the plot

Value

A matrix with the points plotted.
