Dear R People:
I'm trying to compile R-2.15.0 on a 64 bit Windows machine.
However, I'm getting the following error:

set TMPDIR=c:\temp
c:\R64\R-2.15.0\src\gnuwin32make all recommended
make all recommended
make[1]: `MkRules' is up to date.
It is the OPENMP switch. I changed it from -fopenmp to blank and all was well.

It's not a standard format for R presentations, but you can certainly use it.

I need some help with extracting the feature-wise weights from the SVM
object that is the output of *ksvm* function in R (from *kernlab* package).
For instance, if I use the same data/example as the help page does, i.e.,

spam.train -
The forward slashes are to escape quotes and the new lines. Here is

This sounds a little bit like homework (since you know the actual

I'd do something like:

y - 2*n^2 - 5*n + 3
dtf - data.frame(y = y, n=n)
lm( **, data = dtf)
The * should be replaced by a formula object: to find

Dear list,
I would like to subset a large expression matrix based on rownames.
That is, I have a list (as a txt-file) with gene names that matches
some of the rows in my matrix.
I've loaded my matrix as well as gene list using the read.table() command.
myMatrix - read.table(name_of_file.txt,
I think you want:
index - row.names(myMatrix) %in% list_to_keep[,1]
This will give a boolean expression as long as the number of rows in
myMatrix; your original only had a list as long as list_to_keep
