[RFC PATCH v1 0/3] Introducing ARM SIMD Support
libvorbis does not currently have any simd/vectorization. Following patches add generic framework for simd/vectorization and on top, add ARM-NEON simd vectorization using intrinsics. I was able to get over 34% performance improvement on my Beaglebone Black which is single Cortex-A8 based CPU. You can find more information on metrics and procedure I used to measure at

Errors, driving me nuts
Greetings all, I am getting this error that is driving me nuts... (not a long trip, haha) I have a set of files and in these files I want to calculate ttests on rows 'compareA' and 'compareB' (these will change over time there I want a variable here). Also these files are in many different directories so I want a way filter out the junk... Anyway I don't believe that this is

Computation of contour values - Speeding up computation
Dear R useRs, i have the following code to compute values needed for a contour plot ############################################################ "myContour" <- function(a, b, plist, veca, vecb, dim) { tmpb <- seq(0.5 * b, 1.5 * b, length=dim) tmpa <- seq(0.5 * a, 1.5 * a, length=dim) z <- matrix(0, nrow=dim, ncol=dim) for(i in 1:dim) { for(j in 1:dim)

NAMESPACEs and S4 classes
I'd like to have two packages with S4 classes with the same name but different implementation. To that end I create a package tmpA with setClass("A", representation=representation( x="numeric"), sealed=TRUE) setClass("B", representation=representation( x="numeric")) B <- function(...)

How to open more windows to make more graphs at once!
Dear R users, I have a data frame (test) including five columns of upper (numeric), lower (numeric), observed (numeric), best_sim (numeric) and stname (factor with 80 levels, each level with different length). Now I would like to write a short program to draw one graph as follow for each level of stname but I would like also to draw each time 12 graphs for the 12 levels of stname in the same

NAMESPACE & methods guidance, please
My conception of how NAMESPACE and methods in R-2.7.0 resolved a generic 'func' to a func-method was to search as follows: In 2.7.0: func --> NAMESPACE, including Imports: (and other details) --> .GlobalEnv, and eventually Depends: since these are on search() In R-devel it seems like func --> NAMESPACE, including Imports: (and other details) --> ?? but not

Problem with merge() (PR#1102)
I have encountered a problem with merge() that appears to be a bug. Here's an example to illustrate it. > tmp1 <- data.frame(a=letters[1:3],b=LETTERS[2:4],x=1:3) > tmpa <- expand.grid(a=letters[1:4],b=LETTERS[1:4]) > tmpm.1 <- merge(tmpa,tmp1) > tmpm.2 <- merge(tmp1,tmpa) Error in "names<-.default"(*tmp*, value = vnames) : names attribute must

several bugs (PR#918) lists and matrices
### I got bit again by the same bugs I wrote about a year ago. ### The bugs are related to matrices and arrays of lists. ### 1.

[PATCH] qemu-traditional: update configure check for -lrt changes in glibc 2.17
configure uses clock_gettime to check whether -lrt is needed - and don''t check other functions. With glibc 2.17 clock_gettime is part of libc, so use timer_gettime instead, which is in -lrt in old and new versions of glibc.

Dear all, I just installed the new version of R, 2.10.1, and I am currently using the package sparseM. (I also use a 64 bit windows version) I got a problem that I never had: when I try to multiply with a kronecker product (%x%) two sparse matrixes I get the following message: Error in dim(x) <- length(x) : invalid first argument I never had this problem with previous versions of R.

plockstat - chopped stack output
Hi - I''m trying to use plockstat to help identify any mutex contention issues we may have in our c++ app. >From the docs it would appear to be a very useful tool - unfortunately in practice this doesn''t bear out purely because the stack traces produced are limited to being 39/40 characters wide. In general this means that I''m not seeing ~75% of each stack symbol and
