Description

Plot the local maximum matrix of 2-D CWT coefficients returned by getLocalMaximumCWT

Usage

plotLocalMax(localMax, wCoefs = NULL, range = c(1, nrow(localMax)), colorMap = "RYB", main = NULL, cex = 3, pch = ".", ...)

wCoefs	2-D CWT coefficients
range	plot range of m/z index
colorMap	the colormap used in plotting the points
main	parameter of plot
cex	parameter of plot
pch	parameter of plot
...	other parameters of points
