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>

Hi, I am not sure if this is a bug and I apologize if it is something I didn't read carefully in the R extension manual. My initial search on the R help and R devel list archive didn't find useful information. I am using .Call (as written in the R extension manual) for the C code and have found that the .Call didn't release the memory claimed by allocVector. Even after applying

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

I've been attempting to perform some analysis on a model that was interfaced with R (R calls a library that takes SEXPs and converts the data frames into the internal structures of data), and I notice that for small data.frames the vectors don't get corrupt (n<200-ish). When I pass in larger data.frames, the vectors will become corrupt. I've been PROTECTING the heck out of

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 R Users, Thanks in advance. I am using R-2.5.1 on Windows XP. I am trying to call C code (testCX1.C) from R. testCX1.c calls another C code (funcC1.c) and returning a value to testCX1.c. I like to have this value in R. My steps are below: 1. R CMD SHLIB testCX1.c funcC1.c (at command propmt) 2. It creates testCX1.dll with warning (but testCX1.dll works):

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);

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

It's tough to reliably reproduce, but I often get stack imbalance warnings when calling max.col() on non-real/double matrix. The code is conditionally PROTECTing but not incrementing its nprot counter for the eventual UNPROTECT. Pretty sure this would fix (but I haven't tested it): Index: array.c =================================================================== --- array.c (revision

I've been working on a shared library that will be called from R. The functions pass several vectors in and out (residuals, parameters, etc) and I would like to be able to return a list of objects. I'm familiar with return single objects (vectors, etc) from a C function, but need a little help for returning a list of objects. My code so far looks something like: /* this function will

Dear mailing list, I have a C function that gives me a wrong result when I run it under Windows 7.

Heads up: I posted this question on Stackoverflow yesterday (http://stackoverflow.com/questions/26484103/using-a-custom-memory-allocation-function-in-r). So far I haven?t gotten a response and I thought this could be an even better place to ask such a question. I would like to be able to use my own memory allocation function for certain data structures (real valued vectors and arrays) in R. 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/

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
