In NIR spectroscopy, it is common to have at least 1000 variables, and in NMR or MS, you easily get spectra with 20000 variables. You seldom get 1000 spectra, though. :-) 10 to 100 is more common. -- B/H ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
