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

Runtime error when run a RInside program compiled by intel c++ on windows

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:

Controlling stdin and stdout in an embedded R instance
Hello,
I am very new to R but my question is with respect to the C API for
working with an embedded R console. I have been able to start and stop
an embedded R console from within a C program as well as use the API to
execute commands in it. I am seeking a mechanism to individually send
native R commands to an embedded console and then consume the output of
these commands. Specifically, I

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.

mb_m buffer not cleared if parseEval fails
Hi,
I am using RInside for one of the applications that I'm using. The error
that occured is as follows.
When I use R.parseEval("xyz") if the parse fails then the mb_m is not
cleared and hence all subsequent
calls to R.parseEval fail.
example:
when R.parseEval("stringConcatfactoryrandom") is executed the R instance
looks like this
(gdb) p R
$7 = (RInside &)

Embedding R
hello all,
is there somewhere a comprehensive documentation for the (C) functions used for embedded R? (e.g. the functions which are used in the directory \tests\Embedding in the R source)
or
Are there somewhere many more examples for this? (especially handover of data between C and embedded R)
thanks,
Alex

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 :

RInside, rcpp compilation problem
I have spent some hours browsing the RInside and rcpp documentation, lots of it; but ... as a programmer of C++ since 1990, on both Windows and Unix ...

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.

Stop packages and datasets to be loaded on startup.

I would like to know how to start an embedded R session, and avoid

In the paragraph:
I did need however to install Rcpp and RInside from source, and with the same
compiler used to compile qtdensity (otherwise I would get additional linker
errors). As I had trouble getting the (Cygwin-based) g++ shipped with Rtools
to work with Qt, I used instead the
