plotPeak {MassSpecWavelet}R Documentation

Plot the identified peaks over the spectrum

Description

Plot the identified peaks over the spectrum. The identified peaks are returned by peakDetectionCWT or identifyMajorPeaks

Usage

plotPeak(ms, peakIndex = NULL, mz = 1:length(ms), range = c(min(mz), max(mz)), method = c("p", "l"), main = NULL, log = "", ...)

Arguments

ms the MS spectrum
peakIndex m/z indexes of the identified peaks
mz m/z value correspond to m/z index
range the plot range of m/z value
method plot method of the identified peaks. method 'p' plot circles on the peaks; method 'l' add vertical lines over the peaks.
main parameter of plot
log parameter of plot
... other parameters of points
