plotPeak: 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
