Just as note to everyone listening: There are much more official ``R online manuals'' than the one you mention: 1) The most official ones, available by [Manuals] just off the R home page, which goes to CRAN http://cran.r-project.org/manuals.html but these are PDFs which---for the reference manual of all help pages---may be a bit frightening with its almost 2300 pages. Though, actually using acroread's [Find] , entering "Weibull" very quickly brings you to page 1141, and on p.1142 you see the formulae as nice mathematical equations. If you like these real formulae rather than their plain (or Html) text equivalents, I'd like to draw your attention to the much underused help(dweibull, offline = TRUE) which produces a nice postscript help file for the weibull distribution --- if LateX has been properly available when your R was built / installed. 2) The less official ones, particularly for "R-developers" are the help pages for current "R-patched" and "R-devel", available by [Help Pages] off the R home page, which leads you to http://stat.ethz.ch/R-manual/ and there, you'll find (all the manuals, not just) the help pages in the usual ``help.start()'' like form, e.g., http://stat.ethz.ch/R-manual/R-patched/library/stats/html/Weibull.html Martin Maechler ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
