Hi, I have a more complex example, but the problem boils down to this FOR-loop not filling in the res-matrix run_rows<-seq(0,1,0.05) run_cols<-seq(0.3,0.6,0.05) res<-matrix(NA,length(run_rows),length(run_cols)) for(i in run_rows) { for(j in run_cols) { res[i,j]=i+j #niether the above, nor res[[i,j]]=i+j work, why? } } Thank you, Serguei

Hello there, I don't know if I'm addressing my question to the right e-mail address, I hope I do. Actually I have a little problem concerning writing a code in R. I try to briefly sum up my problem.

Dear R developers: When using R.0.99a (Version 0.99.0 Patched (February 9, 2000), source compiled with gcc under SuSE 6.2) on a PIII 500Mhz Machine under SuSE 6.2 Linux I found the following bug: x <- matrix(0,10,0) rbind(x,2) causes an R-crash with the message "Gleitkomma-Ausnahme" (floating point exception) which is probably due to the non-applicability of the recyling

Hi all, I want to use the npudens() function in the np package (multivariate kernel density estimation), but was confused by the several functions in the following codes,expand.grid(),array(),image() and npudensbw(). This confusion will only be generated in >=3 dimensions. I marked the four places with confusion1-4. I think there should be some kind of correspondence in those four

Hi all, Most of time I like to try out wine with game console emulators which use fare amount of d3d or opengls, to see how much wine supports on this.
