plotChrom-methods: Plot extracted ion chromatograms from the profile matrix

Description

Uses the pre-generated profile mode matrix to plot averaged or base peak extracted ion chromatograms over a specified mass range.

Arguments

object
the xcmsRaw object
base
logical, plot a base-peak chromatogram
ident
logical, use mouse to identify and label peaks
fitgauss
logical, fit a gaussian to the largest peak
vline
numeric vector with locations of vertical lines
...
arguments passed to profRange

Value

If ident == TRUE, an integer vector with the indecies of the points that were identified. If fitgauss == TRUE, a nls model with the fitted gaussian. Otherwise a two-column matrix with the plotted points.

Methods

object = "xcmsRaw"
plotChrom(object, base = FALSE, ident = FALSE, fitgauss = FALSE, vline = numeric(0), ...)
