You will find everyhing you want to know in the chapter on statistical models in the manual "Introduction to R". Also look at the online documentation for lm() and maybe nls(). > Then I should like to graph the data (as bullets) and the predicted > function into the same graph. Have a look at the documentation for plot(), line() and predict(). cu Philipp -- Dr. Philipp Pagel Tel. +49-89-3187-3675 Institute for Bioinformatics / MIPS Fax. +49-89-3187-3585 GSF - National Research Center for Environment and Health Ingolstaedter Landstrasse 1 85764 Neuherberg, Germany ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
