looking for adice on bigmemory framework with C++ and java interoperability
I work with problems that have rather large data requirements -- typically
a bunch of multigig arrays. Given how generous R is with using memory, the
only way for me to work with R has been to use bigmatrices from bigmemory
package. One thing that is missing a bit is interoperability of bigmatrices
with C++ and possibly java. What i mean by that is API that would allow
read and write filebacked

r and c++
Hi all,
is there a way to integrate R language within a c++ programme? That is,
is there something like an R library I can incorporate in my c++ code?
Thanks,

Runtime error when run a RInside program compiled by intel c++ on windows
I have intstalled R-3.2.2,Rcpp-0.12.2,RInside-0.2.13 on windows. I compiled the example1 of RInside in the
example directory which create a RInside instance and prints "hello world". The compiler is intel c++. I included
the RInside source files in the project and fixed the compile and link errors. But when run the executable file it
prints some error message and quites.

executable R script under xp (to avoid migration toward Matlab or C++)
Hello,
I discovered R two years ago and thanks to the R-community I managed to
write some scripts to analyze my data stored in mysql databases.
The only problem is that I am the only one using R in the lab. Colleagues
mainly use Matlab (but not with mysql, only with text files) but regularly
come to me to get data treated with R-scripts !!!.
To allow the use of my scripts by other people, my

Embed R code in C++
Hi,
Can anyone tell me how to embed R code in a C++ file.
I am actually using a mac running on the OSX 10.6.2 and the IDE Xcode
Version 3.2 and I would like to embed the basic function like geometric,
binomial, normal and hyper geometric distributions in a sample cpp file.
I heard about the library RInside and i have downloaded the source code for
mac but i do not know how to build it in

About integrating R inside a C++ software
Hi,
We are a company developing a software mainly in C++.
We want to integrate R inside our software in order to use mainly the
engine (usual stats as mean, sigma, Pearson, outlier detection, CPA,
multivariate, ...) and probably later the chart solution.
Of course we don''t want to temporary write the data to some csv files
and then do an ugly system() call :

Dealing with R list objects in C/C++
Hi,
I'd like to construct an R list object in C++, fill it with relevant data, and pass it to an R function which will return a different list object back. I have browsed through all the R manuals, and examples under tests/Embedding, but can't figure out the correct way. Below is my code snippet:

Calling R functions from C++ under VS2005
Hi,
I'm trying to call some of R's statistical functions within my C++
code, developed under VS2005, but I can't seem to find out how to do
it. I tried RInside and Rcpp, but they either don't work on Windows or
with VS. Is there a way to do this?
Appreciate the help.

coerce SEXP type to C++ matrix class and back
Dear all,
I am testing a simple C++ function that takes a double matrix as
argument and which uses routines provided by the C++ Armadillo
package. I am aware of the nice capabilities of Rcpp and RcppArmadillo
which helps simplifying a lot and that I have already successfully
tested. However, I had a hard time trying to figure out how the
coercion from a REALSPX matrix to an arma::mat =

Hello. I am trying to include R in an eclipse C++ project so that I can use

R Lapack – why a subset?
Hi,
Why doesn't R include a full Lapack but only a subset?
My cda package (now archived) relying on RcppArmadillo has broken multiple
times on CRAN over the past few years following updates in the underlying
Armadillo library, Every time it follows the same pattern: Armadillo adds a
function to solve a specialised linear system more efficiently, and the
corresponding Lapack routine is not

O/T good c/c++ code for LU decomposition
Dear R People:
Could someone recommend a good c/c++ code (or Fortran) for LU
decomposition, please?
Sorry to bother about this. I'm trying to do some "non-R" work that
requires a matrix inversion.
Thanks,

Problems to compile examples of RInside

I have some problems to migrate to R >3.0 my devel machine (R.2.15.2). So I decided to start from scratch with a brand new virtual machine.

rhub vs. CRAN fedora-*-devel, using armadillo & slapack
Thank you for your answer.
In facts, 10 threads are asked by armadillo for some LinAlg, which backs to two threads as warned. But I cannot imagine this costs so much time just for that...
A deeper analysis of time spent seems to point that a large time was mainly spent on testthat and Rcpp dependencies compilation... But other recent packages depending on these also are not spending so much time.

RInside & child threads
Hi Folks,
I am creating a multi-threaded C++ application that initializes RInside in
one of the child thread.
I would also like to access support interfaces like Rcpp::Environment in the
remaining child threads, so that I could access any "R" function associated
with the
environment initialized.
When I run my program, I always get "C Stack limit too huge" errors.
