plotS: Plots a matrix representing mass spectra

In ALS: Multivariate Curve Resolution Alternating Least Squares (MCR-ALS)

Plots a matrix representing mass spectra

Description

For each column in a matrix representing mass spectra, generates a sub-plot

Usage

plotS(S, x2, out="", filename=paste("S.", out, sep = ""),
col=vector(),cex=1, lab="",cex.lab=1)

Arguments

S	matrix representing mass spectra of dimension n by comp where comp is the number of spectra
x2	vector of masses that label the rows of S
out	if "", the plot is written to the current device; if "ps" a postscript file is written and if "pdf" then a pdf file is written
filename	character vector specifying the name of the file to write if out=TRUE
col	if length is greater than zero, then the color to plot each spectrum
cex	cex A numerical value giving the amount by which plotting text and symbols should be magnified relative to the default.
lab	cex.lab A character vector used as y-axis label.
cex.lab	cex.lab A numerical value giving magnification to be used for x and y labels relative to the default.
