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-ext doc say, but it still does not work. it is interesting that if i put the R code in the main

Hi everyone, I meet the problem to call R from C. Can someone tell me is it possible to call time series functions(such as ar and arima)from C program on linux platform, and then compile the C program to a standalone executable file? I know we can call some function defined in Rmath.h , but I have not found the entry point for time series function. I would very much appreciate

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

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

Hi all, I'm developing an application on Mac OS X Darwin which embeds R. However, the application always crashes due to the C stack checking. I know that R_CStackLimit can be set to -1 to disable the stack checking, but I don't know where to put the code "R_CStackLimit=-1". Please give some instructions. Thank you very much! Here is my compiler infomation: $g++ -v Using

Dear all, I am using the function 'D' in the 'stats' package to perform symbolic derivation. This works very well and it is much faster than e.g. Mathematica (at least for my purposes). First, I would like to thank the development team for this excellent function. However, I run into trouble in some cases, particularly when I am to do some operations on long expressions

Dear r-devel members, I encountered a C stack limit issue, when I tried to embed R 2.5 into my application. In the R-exts document, it says:"Note that R's own front ends use a stack size of 10Mb". I desire to know: is it possible to decrease this stack size by modifying R's source code? If it's possible, which part of the source code is responsible for the issue? Thank

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. However, my issue is that after having pulled things to a Debian

Dear all, I want to solve a score function by using Newton-Raphson algorithm. Is there such a fucntion in R? I know there's one called optim, but it seems only doing minimizing or maximizing. Thanks, Jimmy

How to use "contour" function? I type "contour(th1,th2,SumofSquares,levels=c(seq(1000,4000,200)))" But I didn't see contour in the plot, I guess it is because my data is so big that contour is out of range. Does anybody know how to fix this problem? here th1 is a 1x101 array(158741.8-298529.6) th2 is another 1X101 array(-0.0058352269-0.2093140935) SumofSquares is a

Hi, I have tried to disable stack checking by set R_CStackLimit to -1. However, it always crashes my win32 multiple threads program. I am using R-2.5.0. My code looks like: #include <Rversion.h> #if (R_VERSION >= R_Version(2,3,0)) #define R_INTERFACE_PTRS 1 #define CSTACK_DEFNS 1 #include <Rinterface.h> #endif and then, add below line to my main function: R_CStackLimit =

Greetings R developers, R will run a little faster when executing "pure R" code if the function R_CheckStack() is modified. With the modification, the following code for example runs 15% faster (compared to a virgin R-2.5.1 on my Windows XP machine): N = 1e7 foo <- function(x) { for (i in 1:N) x <- x + 1 x }

Hi, As the subject suggests, I am looking for the most robust way to call an (arbitrary) function from the R API from another but the main POSIX thread in a package's code. I know that, "[c]alling any of the R API from threaded code is ?for experts only? and strongly discouraged. Many functions in the R API modify internal R data structures and might corrupt these data structures if

Hi All, I am not very familiar with xen details. Now I am thinking of building two privilged domain(domain 0 not driver domain) at boot time. The other question is that wether it is possible to create another domain 0 by domain-builder running in domain0? Does it make sense when domain 0 is shut down unexpectedly another domain 0 can run at once. Maybe it is absurd. I am looking forwards

Apparently the way to deal with this error message is to set R_CStackLimit = (uintptr_t)-1 I tried typing this in the R console, but it says Error: object "R_CStackLimit" not found. So where do I type it? In one of the initialization files that R uses when it starts up? I can't find the answer anywhere. Please note that I don't understand words like "DLL" or

Dear all, Are there any packages can estimate the partial linear model. Or any one can give me any suggestions. Many thanks in advance. Jin
