gelmap {PROcess} | R Documentation |
This function takes its argument as a intensity matrix of a set of spectra and plots the image as a heatmap.
gelmap(Ma, cols = gray(seq(1, 0, by = -0.01)), at.mz = NULL, at.col = NULL, cexCol = 0.2 + 1/log10(nc))
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. |
