Calling R from C - part way there but need a push!
Dear All,
I've read the manual on "Writing R Extensions" and in particular the
part on calling R from C. (Most of the manual is about calling C
from R, not the other way around.)
The good news is that I can now call _some_ R from C, specifically
the R functions which have C header files. However it isn't clear to
me how to call R functions that are written in R. I

rJava fails compilation on R-2.9.1 but not R-2.7.1 on Debian Lenny
I have been futzing around for days tying to get rJava to install on
my freshly build Debian Lenny installation. I have R-2.9.1 installed
from source in my R_HOME directory and R-2.7.1 installed via apt-get
install r-recommended. I was tried many different things, but by
accident started up R-2.7.1 as root and viola, successful install. I
immediately exited out of R-2.7.1 and started R-2.9.1 as

R callbacks
Hi,
I'm trying to understand (mostly from the R-exts manual) how to use
the callbacks declared in Rinterface.h. As a first attempt, I'm trying
to redefine ptr_R_WriteConsole in a very trivial manner. Here's my
code:
---------------
$ cat altr.c
int Rf_initialize_R(int ac, char **av);
#define R_INTERFACE_PTRS 1
#include <Rinterface.h>
extern int R_running_as_main_program;

calling R from within Java, using jri
Hi,
I want to call R from within Java, using jri as per
http://www.rosuda.org/software/jri/
So I am following the instructions in the README file for JRI 0.2-4.
I have run 'sh configure.win' and 'make' and they seemed to be
successful.
(See below for the output from make, for example.)
But when I try 'run.bat rtest' (with and without R command line
arguments)

Embedding R in other applications as a scripting language
I am subscribing to r-core because I am spending more and more time reading
the R implementation itself, but in the meantime I would love to discuss
the topic of embedding R (or linking against it) with more experienced C
developers and people who've written C or C++ code for R packages.
I have reached the stage where to make progress with embedding R in the

question on why Rigroup package moved to Archive on CRAN
Hi,
Who should I ask about my package Rigroup_0.83 being moved to Archive status on CRAN and no longer available via install.package? I have no problems with the move if this was simply because of low demand. However, if there was a build issue with the newest releases that caused problems, I would be happy to address it. I'll just ask my students to install it from my own locally hosted

Plot window does not update in embedded code
Dear list,
I am trying to embed R into a C++ program. After some tinkering,
reading the documentation and browsing the source code I have this
more or less working. A very very condensed and very simplified
version of the code is included below.
The program can create plots. However, after the plot is initially
drawn it is no longer updated. When scaling or updating the plot the
