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

Description Arguments Value Methods See Also

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), ...)
