...sy on BIC, from stepAIC() function help page I found a "k=log(n)" argument to add. Since that produce an error, is there a way to found the "n" dinamically? Why don't add a "k=AIC" or "k=BIC" or something simillary? Thanks in advance, Bye -- Daniele Medri

...N1 <-c(1,2,3,4) N2 <-c(1,2,3,4) N3 <-c(1,2,3,4) abc <-c(1,2,3) the data.frame I want to create: tcm <-data.frame(OneVector, TwoVector, paste("N",1:length(abc))) Obviously :) if I am here this approach doesn't work, so any kind of tip is welcome. Cheers -- Daniele Medri

Dear R.Users, using ctree() (from "party" library) on a data.frame, I want to append a column with the references for the groups/segments detected. While these nodes are easy readable in output, I need a vector for my obs. Hints? Cheers -- Daniele Medri

Dears, I am selecting configure-options for Data Mining applications with R, notes that guide a user from SVN repository to system compilation on GNU/Linux system ("gcc" as compiler). Status: * My system specs: - processor Intel 2.8Ghz HT - kernel Linux 2.6.10-5-686-smp - ram 1500 Mbyte * Dataset to use: - ~900 Mbyte of text file * R from svn repository (daily updated) *

I don't know if this is the right forum, but I'd like to ask an open-ended question about the goals of the S7 OOP system, which is, where do we see the ultimate future of object-oriented programming in R being? Do we see S7 eventually complementing S3 and S4 in "base" (in quotes because S4 is provided by the methods package), or do we see (or even wish?) for S7 to supplant both
