plotPeak: Plot the identified peaks over the spectrum

In MassSpecWavelet: Mass spectrum processing by wavelet-based algorithms

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
