Hi all, I have a problem of Rf_initEmbeddedR function. I've tried with: try { int Argc1 = 1; char *Argv1[] = {"Rtest_1"}; int Argc2 = 1; char *Argv2[] = {"Rtest_2"}; // Init R(first) Rf_initEmbeddedR(Argc1, Argv1); // R package load SEXP e = R_NilValue; SEXP r...

Dear all, I've written a R to python/octave/r translator that (so you can call python from R etc and vice versa) enabling you to e.g. call matplotlib which just runs fine on the first command when I do Rf_initEmbeddedR(2, argv); Rf_endEmbeddedR(0); Rf_initEmbeddedR(2, argv); Rf_endEmbeddedR(0); I get this error Error in .Call("R_isMethodsDispatchOn", onOff, PACKAGE = "base") : Incorrect number of arguments (2), expecting 1 for R_isMethodsDispatchOn Error in gzfile(file) : inv...

Hi All My C++/linux program uses Rf_initEmbeddedR to start R and then calls some R functions. Now I try to port it to Windows. Give the fact that Rf_initEmbeddedR is missing in Windows, I try to use the implmentation in Rserve by Simon Urbanek. When I build in MS Visual Studio, I get the following linking error error LNK2019: unresolved external...

I am trying to use the R API to call optim functions (nmmin, vmmin, lbfgsb, etc.) through a C program but I couldn't find the shared library to link under the R-2.6.0 build which is compiled under Linux (REL5). main.cpp:35: undefined reference to `Rf_initEmbeddedR(int, char**)' main.cpp:41: undefined reference to `nmmin' Thanks in advance for any help. ------------------------ #include <R_ext/Applic.h> #include <R.h> #include <stdio.h> double parabola(int n, double *par, void *ex) { double xm = par[0] - 1; return xm * xm + 13...

Simon, Ah, thank you! quiet right.

Dear All, I'm linking R from another application and embedding it as described in the R-exts manual, i.e. with initialization done via Rf_initEmbeddedR. While everything works the same as in standalone R for Linux, under Windows I found a difference in the default memory.limit, which is fixed to 2GB (both win32 and win64) - compared to a limit in standalone R of 3.5GB for win32 and 16GB on win64 (which is the amount of physical memory I have). So...

Is there a reference guide to the complete set of functions and their arguments that are available in the R.dll library for Windows, i.e. the set of functions that includes "Rf_initEmbeddedR" and "Rf_endEmbeddedR" listed in section 8.2.2 of the Writing R Extensions manual? This may be more of an indictment of my lexical searching skills than anything else, but I was unable to turn up anything comprehensive after an hour with various search engines. -- View this mes...

...c? ========================== On a related note, I found during my PL/R debugging that the segfault was causing the same console based, interactive, "*** caught segfault ***" logic to execute. I was able to confirm that R_Interactive was set to TRUE in my PL/R session. It seems that Rf_initEmbeddedR() sets R_Interactive to TRUE and depends on the output of isatty() to change it to FALSE in Rf_initialize_R() if there is no tty. Unfortunately, the most common methods for starting Postgres leave the tty attached (stdout and stderr are directed to the log file). I ended up explicitly writing &...

So I gather that just setting R_DEFAULT_PACKAGES to NULL should be OK. But then, what is the rather complicated stuff in the autoload() function in littler.c for? And concerning datasets, how do you avoid loading them? All the best, -- Guillaume Yziquel http://yziquel.homel...

i'd like to use the C interface to R in a program i'm writing. as a starting point, i'm trying to create a very simple C program that uses R. i've read the R documentation on this, but i'm having trouble figuring out where SEXP is defined and how to use it. i noticed someone else on this list also tried to use the C interface, but they ran into similar problems:
