gelmap {PROcess}R Documentation

Plot the image of a set of spectra

Description

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

Usage

gelmap(Ma, cols = gray(seq(1, 0, by = -0.01)), at.mz = NULL, at.col = NULL, cexCol = 0.2 + 1/log10(nc))

Arguments

Ma a matrix of intensities; spectra are arranged column-wise.
cols a vector of color to represent continuum of intensities.
at.mz a vector of m/z values where labels are desired.
at.col a vector of sample indices, useful to label particular samples. If NULL, samples will be labelled from down up by 1:ncol(Ma).
cexCol text size of the sample labels.
