Hi, I'm quite knew in R, so I might not have the R specific jargon. But here is my problem, I'm trying to access and use variabels given by a function environment, more specifically the rho in do_optim in src/main/optim.c According to the documentation http://cran.r-project.org/doc/manuals/R-ints.html#The-_0027data_0027 the envsxp is defined as a tagged pairlist. "ENVSXP: Pointers

Hi all, I have a problem but i am not sure that this is the right mailing list. I'm writing a R program which call a C++ program, through the function .Call. I use to compile the c++ script with the command R CMD SHLIB SpTempWrapC.cpp -Wall -l covmodel.h -l util.h Everything works fine since, for mistake, i paste in the terminal the content of the r-script. Now, when i try to compile,

Dear All I'm currently developing a package for R (1.9.0) on Win32, with C++ source code. Having followed the instructions in readme.packages, my code compiles fine with R CMD SHLIB (as well as R CMD check) ... until I start using the internal R functions. (Interesting: Rprintf seems to be the exception.) For instance, the following code compiles fine: #include <R.h> #include

Hi folks, I apologise if this is in the documentation somewhere, but I can't seem to find it. I also did a search of CRAN without any success. I'm using R-1.8.1 (pre-compiled) on Windows 2000 with Rtools and mingw 2.0.0 (which includes gcc/g++ 3.2). I'm trying to link some C++ code from another application to R using the .Call interface and am experiencing some problems. I was

Dear all, I have found some serious bugs in the knnFinder package (which supports data structures and algorithms for both exact and approximate nearest neighbor searching in arbitrarily high dimensions) that may trigger segmentation faults. I have fixed them but I had troubles to contact its maintainer Samuel E. Kemp (previously with the University of Glamorgan, UK). Do someone know where I

Hi, With the sid package jags (2.0.0-1) and r-base-core (2.11.0-1), I cannot install package rjags anymore (this used to work at some point; can't recall exactly at what R/JAGS versions): ---<--------------------cut here---------------start------------------->--- R> install.packages("rjags", configure.args="--with-jags-modules=/usr/lib/JAGS/modules-2.0.0")

There seems to be a latent flaw in the definition of struct SEXPREC in Rinternals.h, which likely doesn't cause problems now, but could if the relative sizes of data types changes. The SEXPREC structure contains a union that includes a primsxp, symsxp, etc, but not a vecsxp. However, in allocVector in memory.c, zero-length vectors are allocated using allocSExpNonCons, which appears to

Hi All, I am new to this area and use Rcpp to call C++ from R and try to build the package under Windows 7. I use Rtools and R 2.10.1 32bit. Everything works fine with me, except using R functions like "rnorm" or "runif" in the C++ code. When I use "R CMD check" the package, it always return error ** libs making DLL ... g++

I am running into a wall getting my system to work with rcpp and inline. Following Dirk's advice on stackoverflow, I hope someone is able to help me. My steps were to install MinGW 32 bit first, then installing Rtools, I disabled MinGW's entry in the PATH. I am trying to get the following code to work: library(Rcpp) library(inline) body <- ' NumericVector xx(x); return wrap(

Dear R-Developers, I just started learning how to use Rcpp. Earlier while using it, I encountered an error as shown below: file74d8254b96d4.cpp: In function ‘Rcpp::NumericVector foo(Rcpp::NumericVector, Rcpp::NumericVector, Rcpp::NumericVector, Rcpp::Function, Rcpp::Function)’: file74d8254b96d4.cpp:10: error: invalid operands of types ‘SEXPREC*’ and ‘R_len_t’ to binary ‘operator/’ make: ***

Dear Group, I'm trying to build a set of new graphic device drivers.

I compile the

Hi, I am Linux Ubuntu 9.04 user. I'm using R-2.6. Actually, I am developing R package for reading/writing 3D images. I needed to use the R package Rcpp in order to make profit of available C/C++ codes. My problem is that my C code is not able to include the Rcpp.h In fact, when I run this command R CMD build rply, I got the following error message in the file

Any idea why CHAR(asChar(STRING_ELT( produces NA whereas CHAR(STRING_ELT( gets a pointer to a string? It's generally expected that STRING_ELT should already be a character, but why the coercion does not work? Here is a simple example (consistent over R2.5.1-R2.6 rev 42284, I didn't check earlier versions, but it used to be different in 2.4): install.packages("inline")

I'm not sure what gave me this idea, but I decided to comment out the swap partition in /etc/fstab and reboot my laptop. I did not run swapoff directly at any time. I'm running more things now than I would ever dream of to hammer my 500MB of memory, but I still notice NO slowdown. This is the best desktop experience I've ever had for any OS on any hardware! Here's the first 12

I found this by accident yesterday. The program that crashes is the first two lines of the example from the help page for nlmer. That example hasn't changed in a long time, so I assumed that it is an R-devel issue. It could also be a long latent nlmer bug. The second run with valgrind is puzzling.

Hello, Suppose I have the function SEXP foo(){ SEXP s; PROTECT(s=allocVector(...)) .... UNPROTECT(1); return(s) } y=foo() // foo is a recusrive call Q: Am i correct in understanding that one does not need to write PROTECT(y=foo()) ?(and a corresponding unprotect later on) since it is the object that is protected , SEXP is an alias for SEXPREC* and allocVector probably does some memory
