similar to: How to disable R's C stack checking

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

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 =

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

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

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 }

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

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

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

Stepan, Andreas gave a lot more thought into what you question in your reply. His question was how you can avoid what you where proposing and have proper threading under safe conditions. Having dealt with this before, I think Andreas' write up is pretty much the most complete analysis I have seen. I'd wait for Luke to chime in as the ultimate authority if he gets to it. The

I can configure it now.

Hi, I am trying to install llvm 2.5 in my PowerPC machine. I have already installed XCode Tools 2.4.1. I can compile programs using gcc run them. I try to configure llvm 2.5, the configuration aborts with following message: checking build system type... powerpc-apple-darwin8.11.0 checking host system type... powerpc-apple-darwin8.11.0 checking target system type... powerpc-apple-darwin8.11.0

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.

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. I looked

CentOS is a really great product, and the package supporters do a bang up job, but the one deficiency I've found is the fact that one can never rely on being able to get updates at any particular time. Whether it's CentOS proper or the Dag additions, something is broke most every time I want to apply updates. I know this is whin[ge]ing, and I certainly don't have a solution to offer.

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.
