In zeehio/MassSpecWavelet: Peak Detection for Mass Spectrometry data using wavelet-based algorithms

Plot the local maximum matrix

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 = ".",
  ...
)

Arguments

localMax	local maximum matrix of 2-D CWT coefficients returned by getLocalMaximumCWT()
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()

Value

No value is returned; this function is called for its side effects (plot).
