With much thanks to Ei-ji Nakama, R 2.5.0 alpha supports building on AIX
(at least AIX 5.2 on one system).
Would anyone able to test this please get the latest tarball from
http://cran.r-project.org/src/base-prerelease/R-latest.tar.gz
and try installing (after reading the AIX notes in R-admin.h
Thanks for your suggestions Douglas,
I just discovered the asInteger, asReal etc. but did not know of
ScalarInteger etc. Will examine these immediately. I am very new to
.Call and SEXP, just started experimenting with these. Previously I
have been using .C for all my functions, transforming a matr

I did read your second message about the problem symptoms disappearing
but I thought that I might make a couple of suggestions about your
code anyway.
There are a number of helper functions declared in Rinternals.h such
as ScalarReal, which is equivalent to your mkans. (Also
ScalarInteger, Scalar

Is there any way to check whether an active binding exists without
actually calling the active binding? I'd like to be able to do
something like exists("x", ...) and know whether "x" exists without
actually fetching its value if it is an active binding (because it could
consume significant res

Hi,
when doing as.double() on an object that is already a double, the
object seems to be copied internally, doubling the memory requirement.
See example below. Same for as.character() etc. Is this intended?
Example:
% R --vanilla

used (Mb) gc trigger (Mb)
Many thanks for the many kind replies. It is very reassuring to have
support from a strong community.

I am glad to hear that there seems to be some commitment for improvement,
although I must admit, that I did not realize that both functions do not
check
if a name is a directory or a filename, even though the definition in "The
Open Group Base Specifications" says:
dirname - return the direct
Hi,
I would like to potentially become involved with this project. I am
still learning about R-project internals but I have been digging
around a lot in the internal R-code. That said, I am initimately
familiar with OOo since I was involved as a volunteer for that
project previously. I

volunteer to help -- otherwise R-core will discuss this.

Still didn't get the point, or missed the topic ?
It's OpenOffice.org and R not Excel and R, two totally different
products at least from a philosophical standpoint. Not everybody is
willing to pay license fee for Excel to be able to use R via a GUI.
That's how the idea was born to integrate or b

Hmm, if all you are interested is reading/writing Excel spreadsheets
from R, there are much lighter and easier ways of doing it, than
hooking up with openoffice. The Perl people have had
Spreadsheet::ParseExcel and Spreadsheet::WriteExcel for years (and
they work quite well, personal experience). T
