gelmap

a matrix of intensities; spectra are arranged column-wise.

a vector of color to represent continuum of intensities.

cols

a vector of m/z values where labels are desired.

a vector of sample indices, useful to label particular samples. If NULL, samples will be labelled from down up by 1:ncol(Ma). 


This function takes its argument as a intensity matrix of
a set of spectra and plots the image as a heatmap.
