subsetting based on vector
Dear R users;
I am trying to write a small program which reads in a data set, and selects
observations from certain years before the analysis. I have a problem
including the selection criteria in the header of the program.
Here is the problem;

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

Varying texts in expression(paste())
Hi,
I am using R a lot to make plots relating to radioactivity, I am often using
expression() to label the plots with nuclide names written with
superscripts, e.g.
expression(paste("Releases of ", { }^{99},Tc," (TBq/year)"))->ywtext
But, is there any simple way to change the number and name of the nuclide
through a variable? I tried
nuccode=expression({ }^{99},Tc)

Problems with rbind
Dear list
I have a simple question that I have a mental block on:
Having used a loop (from i = 1 to n) to assign some numerical values to
row.list[[i]]
e.g. row.list[[3]]= 0 1
I am wanting to combine the output into a simple matrix.
for example, if I combine the output from persons 1 to 3 into a matrix, I
thought I could do :
h<-rbind(row.list[[1]]:row.list[[3]])

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:

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

Quick question!
Thanks very much to all who answered my question
yesterday on loops.
Just a further quick question:
If I have this:

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
