Hi, A quick bench-mark of an R matrix muliplication 500by500 X 500by10000, all random variates, with matlab reveals a huge difference in speed (5 times at least). Is there anything that can be done in R to speed up the multiplication?

Dear all, I get an error using betrag on this data set :http://dl.dropbox.com/u/1866110/dump.csv. I run it like this regression f2.1=betareg(Y~X1+X2,data=dump) summary(f2.1) I get : Call: betareg(formula = Y ~ X1 + X2, data = dump) Standardized weighted residuals 2: Error in quantile.default(x$residuals) : missing values and NaN's not allowed if 'na.rm' is FALSE In addition:

I am experiencing some odd behavior with the .Call interface, and I am hoping someone out there can help me with it. Below is a simple example (in that there are R packages that do exactly what I want), but this code illustrates the problem. Thanks in advance for any help you can provide. Suppose I want to compute the log density of a multivariate normal distribution using C code and the gsl

Anyone know how to esimate parameters in the system: x[k]=Ax[k-1]+ B + Gv[k-1] y[k]=x[k]+Du[k]+Hw[k] a system with exogenous u[k] in the measurement eq., v,w are iid, both eq. are gaussian. Thanks, Oyvind --------------------------------- [[alternative HTML version deleted]]

Hello, Using R-devel (rev 53950), I get inconsistent results with as.environment( VECSXP ) when gctorture is on. Consider: a <- list( aa = rnorm, bb = runif ) gctorture(TRUE) as.environment( a ) The last line sometimes produces the correct environment, but sometimes I get errors. Here are the three situations: # good > as.environment( a ) <environment: 0x100b1c978> # not good

The r2u repository [1] has been providing CRAN packages as Ubuntu binaries (with *full* and *complete* dependency resolution) since last May. It is being served from a well-connect Internet2 mirror thanks to the University of Illinois making it *fast*. By relying on the bspm package [2], it can access the 20k binaries (all of CRAN, essentially, and around 240 BioConductor packages for the two

Dear all, I recently uploaded a new package Rlibeemd to CRAN (http://cran.r-project.org/web/packages/Rlibeemd/index.html, and in github: https://github.com/helske/Rlibeemd), and simple example in help files seems to throw an error on Solaris: Version: 1.3.1 Check: examples Result: ERROR Running examples in ?Rlibeemd-Ex.R? failed The error most likely occurred in: > ### Name:

I'm trying to build an app with clang against libraries that are using GCC 4.1 ABI. I'm getting an error "weakref declaration must have internal linkage" Now I'm stumped though, perhaps it is an incompatibility between clang trunk and gcc 4.1 include files? - I've built clang from trunk - fixed include paths to point to gcc 4.1 include paths When I modify clang to use

When I try to install gsl in R I get the error Need GSL version >= 1.12 . However, I have version 2.3 of gsl installed on the system, which is picked up earlier in the configure process (see below).

I have an upcoming JASA paper with an iid sampling algorithm for Bayesian Generalized Linear models (e.g., Logit, Poisson Regression, and Conditional Logit models with multivariate normal priors). At this point, I have implemented the algorithms in C and hope to make the functions and corresponding source code available through an R package. I have successfully created the code necessary to

Dear R users: I have a problem when installing the R package *gsl*. The procedure is as follows: (1) Since it needs a GSL vesion >=1.12, and the GSL library on the serve I use is too old, I download GSL 1.15 and install it in my own account, such as $HOME/local/gsl. Because I do not have root access, so it cannot be installed in standard folder. (2) Then I download the source code of R

Hi, I'm trying to install the gsl wrapper source code (http://cran.r-project.org/src/contrib/gsl_1.9-8.tar.gz) on a Linux system (OpenSuse 11.1), but encountering the following problem. I've already installed 'gsl' version 1.14 (ftp://ftp.gnu.org/gnu/gsl/gsl-1.14.tar.gz) on the system. What's missing? Thanks a lot... > R CMD INSTALL gsl * installing to library

Hi all, I am new to R and am writing after having contacted Robin Hankin, who maintains the R gsl wrapper. I am trying to use an AFNI (neuroimaging analysis) program that depends on the R gsl package. When I try to use the script I wrote, I get an error that led me to suspect the gsl package was a culprit. When I do library("gsl") within R, I get: Error in dyn.load(file, DLLpath
