TL:DR there are at least three maybe four ways to address this depending on what you plan to do. I usually adjust PATH to add Rtools using .Rprofile. But if you do that then if you want to use the command line to invoke R then you need to set the PATH separately when you start the shell. For this reason some people like to set it in the User Environment Variables control panel... but some Rtools

Hi, I am looking for C/C++ codes for computing generalized inverse of a matrix. Can anyone help me in this regard? Thanks, Mahbub.

Hi Sri, I haven't really elaborated on it having other stuff to prepare first, but as far as I got you first assign data to a vector: #include <R.h> #include <Rinternals.h> #undef R_INTERFACE_PTRS #include <Rembedded.h> #include "Rcpp.hpp" #include <R_ext/Parse.h> #include <Rinternals.h> #include <Rdefines.h> //assigning a vector SEXP

Hi, I have been studying the R manual on lists but cannot seem to create a simple R list in C - I keep on getting "'dimnames' applied to non-array" whenever I attempt to assign names to the list elements: Wanted output a list structure something like [ type="Bid", price=2.0, volume=1000 ] I can get up to a list of [ "Bid2, 2.0, 1000 ] But for the life of

Hi, As was discussed earlier in another thread and as documented in R-exts .Call() should not be interruptible by Ctrl-C. However the following code, which spends most of its time inside mkChar, turned out to be interruptible on RH-7.3 R-1.8.1 gcc-2.96: #include <Rinternals.h> #include <R.h> SEXP foo0(const SEXP nSexp) { int i, n; SEXP resSexp; if (!isInteger(nSexp))

Hi , I am trying to create a dataframe in C and sebd it back to R. Can anyone point me to the part of the source code where it is doing , let me explain the problem I am having . -------------------------------------------------------------------- My simple implementation is like this SEXP formDF() { SEXP dfm ,df , dfint , dfStr,lsnm; char *ab[3] =

Hi , For our production package i need to create a dataframein C . So I wrote the following code SEXP dfm ,head,df , dfint , dfStr,lsnm; *SEXP valueVector[2];* char *ab[3] = {"aa","vv","gy"}; int sn[3] ={99,89,12}; char *listnames[2] = {"int","string"}; int i,j; //============================= PROTECT(df = allocVector(VECSXP,2));

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

Dear list, I am trying to implement a publish-subscribe mechanism in for an embedded R interpreter. But somehow my registered closures seem to get collected by the GC, even though I have protected them. I have reducted my code to the following sample. Sorry if it is a little verbose. The first couple of call of calls still work, but at some point one of the callbacks (callback1 in my

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>

Dear R-lister, is there any function for Meta Analysis in R? (like homogeneity an, risk differences, relative riskm amd odds ratios? Many thanks, Edwin

Can we use the "bytes" encoding for such environment variables invalid in the current locale? The following patch preserves CE_NATIVE for strings valid in the current UTF-8 or multibyte locale (or non-multibyte strings) but sets CE_BYTES for those that are invalid: Index: src/main/sysutils.c =================================================================== --- src/main/sysutils.c

I'm very green with R, so maybe this is not a bug, but it looks like one to me. The following program segfaults at the second call to Rf_PrintValue(). To failure depends on the value of the y-string. E.g., if I change it from "coverage" to, say, "COVERAGE", the segfault does not occur. /* bug.c */ #include <stdio.h> #include <Rinternals.h> #include

Hi guys, I've got a question about the API mkchar(). I have met some difficulty in parsing utf-8 string to mkchar() in R-2.7.0. I was intending to parse an utf-8 string str_jan (some Japanese characters such as?, whose utf-8 code is E381B5) to R API SEXP mkChar(const char *name) , we only need to create the SEXP using the string that we parsed. Unfortunately, I found when parsing the
