It's been a while that I'm not using R under windows but remember had
experienced the same error. I remember that I had to put many paths as
environment variable to build R packages properly.

Hi there,
Problem ::
When one tries to change one or some of the columns of a data.frame, R makes
a copy of the whole data.frame using the '*tmp*' mechanism (this does not
happen for components of a list, tracemem( ) on R-2.6.2 says so).
Suggested solution ::
Store the columns of the data.frame

I would be interested to see how the following approach compares to the other

Daniel,
Check out the promptAll() function in the SoDA package on CRAN.
(Because it was written as an example for my new book, it's not the
fanciest imaginable, but seems to work OK.)

Hello,
I got bungled up by the fact that an infinite POSIXct object is
represented by NA, but is not, in fact, NA. While an infinitely large
POSIXct object seems strange, perhaps R should use the convention of
representing it as Inf rather than NA to avoid any confusion.
Cheers,

This is good, thanks!
I'd like to be able to make sure that the resource is released in conrolled
fasion rather than at some arbitrary gc() call time. Will the following trick
achieve the goal:
foo <-function(whatever) {
on.exit(gc())

could I find it? I had a look at the GNU coding standards on documenting
