I have a question about reference classes, which someone here
undoubtedly can answer immediately, saving me hours of wading through
indecipherable internal code. :-) Thanks in advance.
Reference class data is mutable, fine, but in what sense? Is it really
physical, or is it just a view given
I appreciate Tim's comments.
I myself have a "social science" paper coming out soon in which I felt
forced to use p-values, given their ubiquity. However, I also told
readers of the paper that confidence intervals are much more informative
and I do provide them. As I said earlier, there is no av
Thanks for bringing this up, Frank.
Since many of us are "educators," I'd like to suggest a bolder approach.
Discontinue even offering the stars as an option. Sadly, we can't stop
reporting p-values, as the world expects them, but does R need to cater
to that attitude by offering star display? F

I'm not exactly sure what you are asking, Raymond, but this may answer
your question.
Say you have a file x.cu. After compiling with nvcc -c as you did, then
do something like this:
setenv PKG_LIBS "-L/usr/local/cuda/lib -lcudart"
R CMD SHLIB x.o -o x.so
Thanks very much, Duncan.

here should be information on the line
number at which the user code blew up. It's there in 2.12, but not in
2.13, from what I can see.

too.
You may also find my UseR! presentation on Rdsm to be helpful,

You could do the same thing, though less directly and I believe less
conveniently, using some of the packages Louis mentioned, as well as
bigmemory.

Thanks very much.
By the way, I tried setting a GDB breakpoint at duplicate1(), with the
following:
> x <- 1:1000
> x[3] <- 8
> x[33] <- 88
I found that duplicate1() was called on both of the latter two lines.
I was a bit surprised, since change-on-write would seem to imply that

ewhere that recent R versions make some
attempt to avoid rewriting the entire vector, and my timing experiments
seem to suggest that it's true.
So, is a full rewrite avoided? And where in the source code is this
done?
Thanks.
