James P. Howard,
Hi,
I was using my installed R which is 2.3.1 for the first tests. I
moved to the r-devel tree (I svn up and rebuild everyday) for my by
tests to see if it would work any better. I neglected to retest
merge with the devel version.
So it appears merge is already fixed and I just need to

In any case, as you can see, __libc_stack_end goes away completely by libc
2.3.6, and as noted in the follow-up I sent to this bug yesterday, the
reasons one shouldn't use this symbol are quite clearly stated here:

There was a performance comparison of several moving average
approaches here:

The author of that message ultimately wrote the caTools R package
which contains some optimized versions.
Not sure if these results suggest anything of interest
I wonder if it would not be better to make the user agent string
something that is configurable (at the time R is built) rather than at
run time. This would make Seth's patch about 1% as long. Or this could
be handled as an option. The patches are pretty extensive and allow for
setting the
OK, that suggests setting at the options level would solve both of your
problems and that seems like the best approach. I don't really want to
pass this around as a parameter through the maze of functions that might
actually download something if we don't have to.
