rcode and latex
I have discovered the listings package for including code in your latex documents. The default languages do not include R or Splus, but the definition is pretty simple, this is what I did for R: \lst at definelanguage{R}% {morekeywords={TRUE,FALSE,T,F,NA,NULL,Inf,NaN,library,% attach,detach,source,while,for,in,% repeat,switch,break,next,return,stop,function,% if,else,warning,error},%

Multiv / hierclust / plclust
I use hierclust (hierarchical clustering) in multiv package. In the documentation it is said that plclust (plotting a dendrogram) is available in S-plus. Can I find it anywhere (I have searched through http://lib.stat.cmu.edu/S and found only quotations of plclust in multiv) or is it only part of the S package (which I don't have)? Thanks --------------- Charles RAUX, Laboratoire

Quick question!
Thanks very much to all who answered my question yesterday on loops. Just a further quick question: If I have this: for(i in 1:n) { subset <- data[which(data$id==i),] which returns the rows where I have the variable ID=1, how can I tell the same statement to return just column Y where ID=i? I have tried this for(i in 1:n) { subset <- data[which(data$id==i),data$Y] but it

Scoping rule problem -- solved
Thanks to some comments from Brian D. Ripley, I found my error: I should not have given a data argument to lm() after creating a formula-object. This obviously confused things...

hclust question
Dear all, I have a question with regard to the use of hclust. I would like to be able to specify my own distance matrix instead of asking R to compute the distance matrix for me. It is computationally easier for me this way. My question is: How can I get hclust to accept this? Thanks, Ranjan -- *************************************************************************** Ranjan

Editing R graphics
One of the few things that I miss from Splus is the ability of interactively add text and symbols to graphics that have been created by functions. I understand that the best solution in R is to create a graphic file and use external software for editing the graphic. I know what to use in the Win environment, but could anyone suggest what tools would be appropriate under Linux? Thanks Agus Dr.
