Usage of OCaml/R binding.

Hello. I've been pulling together a Debian package out of Maxence Guesdon's OCaml bindings for R. Will be available from my website as soon as I get my router to obey me. Here's Maxence's bindings: http://pauillac.inria.fr/~guesdon/ocaml-r.en.html The purpose of this software is to access R from OCaml programs.

About " Error: C stack usage is too close to the limit"

Hi everyone! I meet one problem when embedding R in C code, when I run the the R code in one child thread , it always print error info: Error: C stack usage is too close to the limit I also try to set R_CStackLimit = (uintptr_t)-1 to disable the C stack check as the R-exts doc say, but it still does not work, the error info still exist. Besides it is interesting that if i

Parsing code with newlines

Hello! This is my first post here. I came across the very same problem. It can be reproduced within modified tests/Embedding/RParseEval.c Actually this example has another issue, namely it doesn't wrap everything in R_ToplevelExec . This is a major show stopper for newcomers as that function is barely mentioned anywhere and longjmp into terminated setuploop function followed by R_suicide

Simon, Ah, thank you! quiet right. For anyone searching for this in the future, I changed my init fuction to: ---------- SNIP ---------------- void init_r() { SEXP aperm_function; /* this is our version of Rf_initEmbeddedR where we disable stack checking */ const char *init_argv[] = {"MyFront", "--vanilla", "--slave"}; Rf_initialize_R(sizeof

Child thread libR.so

So I'm working on a custom front end to R, in one mode of the front end I dynamically load libR.so into a child worker thread. I'm very careful to make sure it is loaded by a single thread and loaded only once, but since it is a child thread it violates assumptions made by the stack size checking inside of R and I get innumerable errors along the lines of Error: C stack usage

Redefinition of _res in getrrsetbyname.c

I've been trying to figure out why I can't seem to use SSHFP fingerprints delivered via DNSSEC, which led me to try to figure out why OpenSSH won't use DNSSEC on my NetBSD-4-branch platform. It turns out that around line 70 in openbsd-compat/getrrsetbyname.c, we have the following: /* to avoid conflicts where a platform already has _res */ #ifdef _res # undef _res

I did some poking around with GDB and confirmed that the advice of setting R_CStackLimit after init, which is echoed in the "threading issues" section of the R-exts help document, isn't entirely useful because init apparently loads the main package which trips over the broken stack checking.

simple example of C interface to R

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:
