Yes, Mavericks build is incompatible with the Snow Leopard build, that's why

you're interfacing a foreign runtime system (language or library). What is or

In addition to the major points that others made: if you care about speed,
don't use compression. With today's fast disks it's an order of magnitude

Since you only provided part of your code we can't really reproduce it or help

If you really want to use Windows, I have fixed the Windows build so it should
work, but you'll have to configure it by hand -- but as I said, I strongly

Jordi,
I think you are misunderstanding a few things here. First, "R" doesn't endorse
anything - it is a program, it does what you tell it to do. Second, whoever
runs R-forge doesn't endorse the packages hosted on it, either. It's just an
infrastructure, with no claim about endorsement of the p

IMHO this has nothing to do with capture.output() per se - it's simply lazy
evaluation that gets you. Add force(envir) before capture.output and it works
as you expected - the parent.frame() will be different inside capture.output
than outside.

Dan,
I don't know why, but something is off in the recent R-devel build for ppc. The
result is that the installed binary ppc is older than the other ones, so it
doesn't have paste0 while the others do.
The really strange thing is that the build logs show success, but the build
directory is old
Barry,
that's a great idea. I have created a package that allows you to read/write
passwords to user's keychain:
http://www.rforge.net/keychain
So far it uses the Security framework so you'll need a Mac, it but I'm about to
add a generic fall-back system (encrypted file on-disk) and possibly t

Hadley,
there was a whole discussion about subsetting and subassigning data frames (and
general efficiency issues) some time ago (I can't find it in a hurry but others
might) -- just look at the `[.data.frame` code to see why it's so slow. It
would need to be pushed into C code to allow certain
