I am struggling to find the root of a non-linear monotone function. "uniroot" is complaining about a missing argument? + f.lower = -0.2724897, f.upper = 7.515328, + mu = 7462.83, shape = 0.4475635,
Thanks to Dimitris Rizopoulos, Bill Dunlap and Christos Hatzis who responded so quickly. The problem was that "uniroot" has an argument called "keep.xy" and, due to S's partial matching of arguments,
when using the merge fonction as follows I am expecting the output to have the same number of rows as the "x" data.frame, I am obviously missing something?? Where do the extra rows come from? ttt <-
Thanks to all who responded: Francisco Javier Aguirre Navarro, Matt Austin and Bill Dunlap. The answer was simple, the rows of the "y" data.fame were not unique w.r. to the merging variables and henc
Hello there, I routinely work with huge data sets in S+, over 2GB, on a Unix machine with 8GB of RAM. The best way I have found to import the data sets, without using too much resources, is to pre-al
Hello everyone, many people requested the function, hence I am posting it on the list. Please note that I am not the original author, but Stephen Weller's of Insightful is; I am a firm beleiver of gi

anyone aware of an implementation of variable clustering in Splus, something similar to "varclus" in SAS? Thanks, Gérald Jean Conseiller senior en statistiques, Actuariat télephone : (418) 835-4900
I am trying to use the "varclus" function from F. Harrell's Hmisc library. Trying to run the example from the help page I get the following error. x1 <- rnorm(200) x2 <- rnorm(200) x3 <- x1 + x2 + r
Frank was right. I was attaching my own version of Hmisc, don't ask me why I had a private version, I can't recall? All I can tell was that I was, routinely, issuing the command: = '/actuaria/jeg002
I sent the following on Friday, it was rejected with the reason: " Please resend without the graphic file - it does not add to your posting." But there was no graphic file attached to my posting???
Hello there, I am playing with the trellis postcript device for several hours now and I can't get it to work the way I wish it would. I have a function I have been using for several years without pro
