similar to: .Call and to reclaim the memory by allocVector

Hi R-Users I wrote 1 week ago asking about a message that appears when I try run dyn.load. I'm trying to do an example in C code from "Writing R Extension" to learn how to do it. I have R 2.0.0, Rtools, Perl and MinGW as describe in http://www.murdoch-sutherland.com/Rtools/ with path sets. When I use C:\R\rw2000\bin>RCMD SHLIB -o C:/dev-cpp/teste.dll

Hi! I am studying C language to run with R 2.0.0. My system (Windows ME /BR) is configured to run RCMD ( I have installed ActivePerl, Rtools and MinGW as indicated in http://www.murdoch-sutherland.com/Rtools/ an with correct path). I would like run the coded write below named conv.c (Example from "Write R Extension") : #include <R.h> #include <Rinternals.h>

I'm continuing my work on finding speedups in generalized inverse calculations in some simulations. It leads me back to .C and .Call, and some questions I've never been able to answer for myself. It may be I can push some calculations to LAPACK in or C BLAS, that's why I realized again I don't understand the call by reference or value semantics of .Call Why aren't users of

Hello, Can anyone help on gsub() in R? I have a string like something below, and wanted to delete all the strings with leading backslash, including "\xa0On", "\023, "\xab", and many others. How should I write a regular expression pattern in gsub()? I don't care how many characters following backslash. txt <- "Is This Thing\xa0On? http://bit.ly/jAbKem

Hi everyone, I can't figure out how to extract by-factor random effect adjustments from a gam model (mgcv package). Example (from ?gam.vcomp): library(mgcv) set.seed(3) dat <- gamSim(1,n=400,dist="normal",scale=2) a <- factor(sample(1:10,400,replace=TRUE)) b <- factor(sample(1:7,400,replace=TRUE)) Xa <- model.matrix(~a-1) ## random main effects Xb <-

Hi, everyone, I am just trying to use Rcpp in my computer, and I would like to try a simple example from website, but R keeps reporting me error. I am using Windows XP, and has installed Rtools and GSI. Here is the response: > src = ' + Rcpp::NumericVector xa(a); + Rcpp::NumericVector xb(b); + int n_xa = xa.size(); + int n_xb = xb.size(); + + Rcpp::NumericVector xab(n_xa + n_xb - 1);

Hi, I'm just wondering how I can do to make a huge postscript plot be manageable. My question is that I have to draw around 60,000 points which makes it painfully slow to print or view in gv or put it into latex document, though it is very fast to produce the postscript file. A simple example is in the attachment. Well, I found that if I use png or jpeg. It is much faster to view the

Hi all, >From the manpage of rsync, I can see the following descriptions: --inplace The option implies --partial (since an interrupted transfer does not delete the file) So I do the following testings on the `--inplace' and `--partial' for resuming a file with the following steps: 1- rsync ftp.cn.debian.org::debian/dists/wheezy/main/binary-amd64/

Hello, We have a nodejs app which is injecting first boot scripts using virt-customize however the exact same commands are working when triggered manually.

Everyone, I have a mail server running CentOS release 6.3 (Final) with 2.6.32-279.22.1.el6.i686 kernel that is reporting errors to me pertaining dovecot. I have appended the error message to this note. There is only one user that appears to generate this message, and it is generated to me by way of e-mail without a perceptible problem to the user which is not me. This particular user had an

Before this patch, Python would segfault once you pass a non-string key or value to node_set_value. It was also not possible to set bytes on Python 3 as Unicode was assumed (Python 2 was not affected by this). This patch fixes recognition of bytes for Python 3, but in addition it recognizes ints (includes 'long' in Python 2) for DWORD (LE + BE) and QWORDs. For this purpose, a new field

Guys, Dovecot 1.0.15 [1], just built the latest antispam-plugin 1.2 (tarball) for testing, mailtrain backend for SA integration. Both built from custom spec files. The mail that is being trained is different than its respective source in the mbox file. The trained one shows added, trailing carriage-return chars for all headers, which are not in the headers in the mbox file. This breaks sa-learn

Hi, I'm trying to write a function to return an R vector which points directly to a contiguous subset of another vector, without taking a copy. Since SEXPREC is a header followed by the data, rather than the header plus a pointer to the data, I'm not sure what I'm trying to do is possible. Is there a way of doing this? Similar in spirit to how the R assignment "x=y" does

Hi, getMetadata(“dbg”) returns NULL for such a small program as follows: int main(){ char a[10], b[2]; if(a[0] != 0 && a[1] != 0){ strcpy(a, b); } return 0; } The compiling command is: llvm-gcc --emit-llvm -g -c ./src.c I also tried the solutions I found through Google: http://stackoverflow.com/questions/14943447/llvm-line-number-of-an-instruction

I recently had some scary experience with the Inbox being stored in the default /var/mail dir, and I believe it would be a better idea to keep the Inbox next to any other mail in the users $HOME. mail_location = mbox:~/.mail:INBOX=~/.mail/INBOX This is what I used for a quick test, and actually would love to use in production soon. Based on the test, it just does exactly what I want. :)

Hi dear R-users I try to reproduce the steps included in a LDA. Concerning the eigenvectors there is a difference to SPSS. In my textbook (Bortz) it says, that the matrix with the eigenvectors V usually are not normalized to the length of 1, but in the way that the following holds (SPSS does the same thing): t(Vstar)%*%Derror%*%Vstar = I where Vstar are the normalized eigenvectors. Derror

Hi I'd like to generate thousands of normal numbers from my C function using the C API functions provided R. I have two options: 1. double norm_rand(); (page 61 of R extension 1.8.1) 2. double rnorm(double mu, double sigma); (page 58 of R extension 1.8.1) If my understanding of R-exts is correct, then I only need to call GetRNGstate once, and then call 1000 norm_rand, and then call
