You should learn to use help.search() {yes, everyone, even if you prefer the HTML help pages!!} In this case, even if you only have the default packages (standard + Recommended), you'd get > help.search("monotone") Help files with alias or concept or title matching 'monotone' using fuzzy matching: mono.con(mgcv) Monotonicity constraints for a cubic regression spline. isoreg(modreg) Isotonic / Monotone Regression backSpline(splines) Monotone Inverse Spline which is probably sufficient. -- Martin Maechler <[EMAIL PROTECTED]> http://stat.ethz.ch/~maechler/ Seminar fuer Statistik, ETH-Zentrum LEO C16 Leonhardstr. 27 ETH (Federal Inst.
