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

sorry!~I have a question
I have a question.
I can find a function about "Gaussian hypergeometric function" in sofeware Maple V.
I need this function to calculate.
Is there a similar function in R ?
Or I have to design such a function.
Thanks!

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]])
However, I get the

Does anyone know of an R proc to export matrices or data frames (preferably

density(x)
Dear experts,
when trying to estimate an kernel density function with density(x) I get the following
error message with imported data from either EXCEL or text files:
Error in density(spr) : argument must be numeric.
Other procedues such as truehist work. If I generate data within R density works fine.
Does anybody have an idea?

Warning message:

panel.loess
Hi,
I'm not sure what the recommended thing to do here would be:
In the lattice library, panel.loess needs to use loess.smooth(), which is
in the modreg library. Now should I
(1) make lattice depend on modreg, and call require(modreg) in zzz.R
OR
(2) use autoload("loess", "modreg")
I like the second option better, as a particular session might not need
panel.loess.

Constructing titles from list of expressions
Hello!
I have the following problem:
I have a function to construct three surfaceplots with a marker for an optimum,
each of the plots has as title paste("Estimated ",pred.var.lab," for
",var.lab[1]," vs. ",var.lab[2],sep="") with different var.lab[1,2] each time.
My problem is now that I need to allow for plotmath expressions in the
variables pred.var.lab

Loess
Hi,
I am using Loess.smooth (Modreg) in order to infer certain relationship
for the data set of ~130,000 observations with ~300 distinct values of
single predictor. I understand that fitted values (y-hat) are just 300
Weighted LS fits in certain neighborhood of predictors. I am bit confused about
how exactly is this neighborhood assigned . Say I choose spanning
parameter = .5, for each LS

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:

attach,detach,source,while,for,in,%
repeat,switch,break,next,return,stop,function,%

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

Document R sourcecode with Tex
Hi,
I'm actually afraid that this is a RTFM question - I read the manual but
didn't find anything yet... I'm looking for a way to document R sourcecode
in my thesis. Does anyone know of a tool or function which can convert or
export R sourcecode to Tex?
Thanks for any hints!
