...the included liblzma is used instead of a system wide one, so it might not be worth the trouble of patching the sources instead of waiting for a new release. If anyone wants to apply a fix, I have prepared a patch with all the changes which can be found here http://www.statistik.tu-dortmund.de/~olafm/temp/xz_restrict.patch Cheers, Olaf Mersmann

Hello all, I'm new to R (and the S language in general) so go easy on me if this is really simple. Given a data.frame df which looks like this: f1 f2 f3 f4 c1 c2 1 y y a b 10 20 2 n y b a 20 20 3 n n b b 8 10 4 y n a a 30 5 I'd like to aggregate it by the factors f1 and f2 (or f2 and f3, or any other combination of the three) and compute the sum of c1 and c2 (as separate values). I

I've integrated some DTrace [1] probes into R. Namely a probe which fires on fuction entry and return and one which fires before / after a garbage collection. Is there any interest in merging something like this into R-devel? If yes, I'd like to discuss which probes and what data would be useful / interesting from a developers standpoint. Greetings from Dortmund, Olaf Mersmann [1]

Dear R-developers, I find the current behavior of Negate() somewhat confusing. It does not match the passed function 'f' until the returned function is called for the first time. To see an example of what this can do see the following (contrived) example: f <- function(x) is.integer(x) not_f <- Negate(f) f <- function(x) is.character(x) ## Both should, in my mind,

Dear R developers, A recent typo led me to discover, that R is happy to accept > 20x2 [1] 20 as input. This appears to be related to the parsing of hexadecimal constants, since there must be a zero before the 'x' (i.e. 2x2 or 02x02 gives the expected error). All this is under R 2.12.1 on both OS X and Linux. Is this expected behavior? Cheers, Olaf Mersmann
