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

I wonder if there is a R mode for emacs which highlights the R syntax.
If there is one, I would be interested in downloading the latest version

Graphics
Please, will someone tell me why graphics are not displayed at all when
I use a graphical function. Is there some additional software required
to see the graphics?

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]

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...
Thanks again, I've really learnt again a bit more on R-programming...
Cheers, Winfried

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

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
