Hello, the included XZ Utils source code contains an incorrect use of the restrict keyword. This leads to data corruption under certain circumstances. For a short discussion of the problem see http://sourceforge.net/projects/lzmautils/forums/forum/708858/topic/3306733 This was fixed in the XZ Utils git repository in commit commit 49cfc8d392cf535f8dd10233225b1fc726fec9ef Author: Lasse

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

Hi list, not sure if this is the wanted behavior, but running the following code: > version platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor 1.1 year 2005 month 06 day 20 language R > n <- 500 > d <- 4 > m <- matrix(runif(n*d, -1, 1), ncol=d) > c <- hsv(apply(m, 1, function(x) {sum(x*x)/d}),

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,

Hi, `model.matrix' might kill R with a segfault (on a illposed problem, but anyway): mydf <- as.data.frame(sapply(1:40, function(i) gl(2, 100))) f <- as.formula(paste("~ - 1 + ", paste(names(mydf), collapse = ":"), sep = "")) X <- model.matrix(f, data = mydf) *** caught segfault *** address 0x18, cause 'memory not mapped' Segmentation fault

Hi, I believe I have significantly improved [dpq]wilcox functions by implementing Harding's algorithm: Harding, E.F.

I've rolled up R-2.12.2.tar.gz a short while ago. This is an update release, which fixes a number of mostly minor issues, and one major issue in which complex arithmetic was being messed up on some compiler platform. You can get it from http://cran.r-project.org/src/base/R-2/R-2.12.2.tar.gz or wait for it to be mirrored at a CRAN site nearer to you. Binaries for various platforms will

I've rolled up R-2.11.1.tar.gz a short while ago. This is an update release, which fixes a number of mostly minor issues. The most annoying one was probably the problem with format.POSIXlt causing C stack overflow on long date vectors. See the full list of changes below.

Forgive my resending this post. To data I have received only one response (thank you Bert Gunter), and I still do not have an answer to my question. Respectfully, John Windows XP R 2.12.1 contrast package. I am trying to understand how to create contrasts for a model that contatains an interaction. I can get contrasts to work for a model without interaction, but not after adding the

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.

Being italians when writing comments/instructions we use accented letters - like ?, ?, ?, etc.... when running R scripts using such characters I get and error saying: invalid multibyte character in parser I have been looking at the help and searched the r-help archives but I haven't find anything that I could intelligibly apply to my case. Can anyone suggest a fix for this error? Thanks,
