Rcpp with OpenMP - Need example Makevars
Dear R experts,
recently I started developing a Rcpp package "OpenMPTest".
Within that package I want to use OpenMP, as in the following code example:
// header file
#include <omp.h>
using namespace Rcpp ;
RcppExport SEXP testOpenMP( SEXP nThreads ) ;
// cpp file
SEXP testOpenMP( SEXP nThreads ) {
BEGIN_RCPP
NumericVector numberThreads = NumericVector( nThreads );

reference classes, LAZY_DUPLICATE_OK, and external pointers
We (the lme4 authors) are having a problem with doing a proper deep
copy of a reference class object in recent versions of R-devel with
the LAZY_DUPLICATE_OK flag in src/main/bind.c enabled.
Apologies in advance for any improper terminology.
TL;DR Is there an elegant way to force non-lazy/deep copying in our
case? Is anyone else using reference classes with a field that is an
external pointer?

Help with integrating R and c/c++
Hi,
I have been using R for close to two years now and have grown quite
comfortable with the language. I am presently trying to implement an
optimization routine in R (Newton Rhapson). I have some R functions that
calculate the gradient and hessian (pre requisite matrices) fairly
efficiently. Now, I have to call this function iteratively until some
convergance criterion is reached. I think the

RSPerl...
Duncan -
(but sent to R-devel, for any other thoughts?)
How do you envision RSPerl being used? Without having seen the
details, I can think of playing with strings; is there a preferred
incantation for stringification of R objects (serialization)?
(actually, the main problem I'm having is that I know how I want to code

Rcpp segmentation faults on the simplest code

Issue when calling deparse(substitute(x)) from C with "anonymous" R vectors ?
Dear list,
When calling R from C, what appears like a spurious error can be
triggered during the execution of chisq.test(x, y).
This is happening when the following conditions are met:
- x and y are "anonymous" C-level R vectors (they do not have a symbol),
but they are protected from garbage collection
- x and y are "not too small" (it was experienced as soon as they are

tcltk wish: Add tclObj.raw method for converting raw vectors to tclObj
Greetings,
I have submitted a bug report / wish to the R Bug tracker (https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14939), but I'd like to make this request here as well. Essentially, I was wondering if it would be possible to add another c routine to be called by as.TclObj for raw vectors. Right now, as.raw() is supported for objects of type "tclObj" (IIRC this change was

binary to R object
Hello,
I have stored R objects as hexadecimals in a mysql database, I then usually transform them to binary and then save it into a file. E.g.
hex <- getBlob #gets blob from database as hexadecimal
binary <- transformToBinary(hex) #moves from hex to binary
I would usually save them into a file as follows:
writeBin(object=binary,con="fileName.txt")
