Plot extracted ion chromatograms from the profile matrix
plotChrom-methods.Rd
Uses the pre-generated profile mode matrix to plot averaged or base peak extracted ion chromatograms over a specified mass range.
Methods
- object = "xcmsRaw"
plotChrom(object, base = FALSE, ident = FALSE, fitgauss = FALSE, vline = numeric(0), ...)
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.
