grep and PCRE fun
Hello,
I think I've found a bug in the C function do_grep located in
src/main/grep.c. It seems to affect both the latest revisions of
R-2-13-branch and trunk when compiling R without optimizations and
with it's own version of pcre located in src/extra, at least on ubuntu
10.04.
According to the pcre_exec API (I presume the later versions), the
ovecsize argument must be a multiple of 3 ,

.Renviron for multiple hardwares...
Our lab has a lot of different unix boxes, with different hardware, and
I'm assuming (perhaps wrongly) that by setting a per-user package
installation directory, the packages will only work on one type of
hardware. Our systems are all set up to share the same home directory
(and, thus, the same .Renviron file) -- so, is there a way to set, in
the .Renviron file, per-computer or

Best way to determine if you're running 32 or 64 bit R on windows
Hi,
Is this sufficient?
if (.Machine$sizeof.pointer==4){
cat('32\n')
} else {
cat('64\n')
}
Or is it better to test something in R.version, say os?
I'd like to use this to specify appropriate linker arguments when
building the RMySQL windows package.

Should this PDF render correctly without font embedding?
A professor here at Vanderbilt sent me the following code. Each of the
text strings should right justify against the center vertical bar, but
because of font issues it doesn't. I understand that there are
workarounds, but I was just curious if this was consistent across all
platforms. On linux with R 2.7.1 and R-trunk (r46103), both acrobat
reader 8 and kpdf render it incorrectly. How

Possible bug in Rcons_vprintf
In R-2-4-branch r39548, Rcons_vprintf is called from stdout_vfprintf
when R_Outputfile is NULL. When called and output is greater than
R_BUFSIZE, output is truncated to R_BUFSIZE. Here's a one-line fix:

I made sure that the implementation passed 99% of the tests, however
there were two that gave differing results which I think are related

Will PrintWarnings remain non static?
Hi,
The C function PrintWarnings is currently not in the C API, but it is
declared non static in the svn trunk as of revision 53110 . As this is
the only function that creates the last.warning object used by the R
function warnings(), I think it would be useful for programs that
embed R to be able to call it.
So, will it remain non static, that is callable although it's not
declared in the

parse_Rd raises error when example section contains a quoted percent character
I was writing Rd documentation for a new package when I came across
this issue. Here's the smallest example:

Subtle bug in do_basename
Hello,
I've been wondering why my no-optimization R-devel builds have been
hanging during "building/updating package indices ...". I tracked it
down with gdb to this line from do_basename in utils.c:
while ( *(p = buf + strlen(buf) - 1) == fsp ) *p = '\0';
Now, imagine if your compiler places the variable fsp immediately before
buf on the stack, and strlen(buf) is 0.

R graphics device for flash apps
Byron,
I just read your blog (statcomp.blogspot.com, linked from your other
post) and rand across your idea of an R/Flash graphics device. I've also
been giving this some thought because of this amazing interactive flash app:
http://tools.google.com/gapminder
and others from http://www.gapminder.org/.
I would love more than anything to work on this. The only hitch is that

Struggling with S3/S4 interface issues and External Pointers
I'm currently working on embedding R into the Apache2 webserver (with
some positive results...), but I'm struggling to identify the best way
to expose the apache data and functions to R.
A couple of thoughts:
In light of the recent discussion on "S3/S4 classes performance
comparson", I'm leaning toward implementing the interface with S3 style
classes. I appreciate

Creating a reference class object from a class definition in a package fails
Hi,
I'm trying to create a package that contains reference class
definitions from which users can create reference objects, but there
seems to be something awry.
My toy example creates an empty package via
package.skeleton('TestClass') to which I add the following R code:
TestClass <- setRefClass('TestClass',fields=c('name'))

Adding difftime objects to POSIXt objects
Hello,
?DateTimeClasses states that "one can add or subtract a number of
seconds or a 'difftime' object from a date-time object, but not add two

Overriding InitTempDir
For embedded projects, one may want to eliminate the per-session temp

{
char *tmp;

if (rmdir(R_TempDir) != 0){
