Dear List,
I have a Date vector, and converting to character causes R 2.11
to crash on one machine running Win2008 x64 and another running Win7 x64.
The code runs fine on R 2.10.
For example,
x <- as.Date(rep(1:15000, 10), '1970-01-01')
y <- as.character(x)
At this point, Rgui crashes.

I just did a little test and found, in the case of gcc/g++, that a

I think so - at least on the exceptions t
Thanks for the clarification Simon,
I think it is safe (R-safe?) to say that if there are no exceptions or errors
on either side, then it is highly likely that everything is fine.
When there are errors or exceptions, it is probably NOT safe to try to
recover. Better to terminate the R session, in

Simon,
Just to be sure that I understand, are you suggesting that the R-safe way to do
things is to not use STL, and to not use C++ memory management and
exception handling? How can you leave a function in an irregular way without
triggering a seg fault or something like that, in which case there
Hi Folks,
I am creating a multi-threaded C++ application that initializes RInside in
one of the child thread.
I would also like to access support interfaces like Rcpp::Environment in the
remaining child threads, so that I could access any "R" function associated
with the
environment initialized.
Hello dear members of R-devel mailing list and Kevin Buhr (the author of
the polygon function),
After some private e-mails, I was informed this is the place to post this
feature request. I hope I am correct.
I would like to use a command like this:
plot(c(1,8), 1:2, type="n")

My script is very NEWS specific. The manuals would be harder. You

Maybe Duncan could apply the same script that's being used for RNEWS
to the manuals? An RSS feed of changes to the manuals would be really
useful.

Brian's answer was pretty exhaustive - just one more note that is indirectly
related to memory management: C++ exception handling does interfere with R's
error handling (and vice versa) so in general STL is very dangerous and best
avoided in R. In addition, remember that regular local object rul
