Description

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.

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.

Methods

object = "xcmsRaw"
