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, 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

Kernel 2.6.38 has adopted a format called XZ for kernel use, as well as some filesystems. Format appears to be optimized for streaming and embedded use. I'll happily test it if anyone wants to plug in some code for it. http://tukaani.org/xz/format.html http://kernelnewbies.org/LinuxChanges -------------- next part -------------- An HTML attachment was scrubbed...

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

In a recent commit guestfish changed the default size for disk images prepared using the -N parameter from 100M to 1G: https://github.com/libguestfs/libguestfs/commit/adc23829e4b128562c2c29d984654528bd259644 For the xz plugin test we prepared a disk image using guestfish and then xz-compressing the output, but we did not take our own advice and use the --block-size parameter to limit the xz

FYI; I'm going to push this because it's such an obvious fix. Rich.

Hello, The attached patch adds bzip2 and lzma/xz libs to stubdom for pvgrub. This is the first step of getting the additional compression methods supported in pvgrub. There''s still some Makefile voodoo to sort out before pvgrub actually properly gets linked against these new libs. This patch only adds the libs and makes them build. -- Pasi

Hello, Just wondering: Dovecot has gzip/bzip2 compression/decompression support. According to this: http://stephane.lesimple.fr/wiki/blog/lzop_vs_compress_vs_gzip_vs_bzip2_vs_lzma_vs_lzma2-xz_benchmark_reloaded gzip and bzip2 aren't really useful together. While gzip can offer speed and a reasonable amount of compression ratio, bzip2 is slow, especially on decompression, which Dovecot does

Timo, Thoughts on adding LZMA2 (xz) support via liblzma to Dovecot? -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
