I'm having a problem with the error and warning functions. I've tried this on multiple machine so I'm fairly sure it's not machine dependent and I've tried it on the latest versions 2.6.0-2.7.1. Whenever my program gets to an error or warning it crashes the entire program rather than throwing the error like it should. Here are the relevant bits. ... char const * const

To anyone following the Windows toolchain saga: The gcc 4.9.2 toolchain that is currently in Rtools33 has too many incompatibilities with existing code, so we won't be using it in the R 3.2.0 build. I will soon be uploading to CRAN a new version of Rtools33 that is very similar to Rtools32, containing gcc 4.6.3. We are continuing to work on the new toolchain, and hope to have it ready

Hi, at the R prompt, is it possible to retrieve the last error (as in condition object of class "error")? I'm not asking for geterrmessage(), which only returns the error message (as a character string). I'm basically looking for a .Last.error or .Last.condition, analogously to .Last.value for values, which can be used when it is "too late" (not possible) to go back

WRE explains that R_alloc() can be used to allocate memory which automatically gets released by R at the end of a .C, .Call or .External, even in the case of an error or interruption. This is a really great feature to prevent memory leaks. I was wondering if there is a way to extend this mechanism to allow for automatically running UNPROTECT and custom finalizers at the end of a .Call as well.

I have a function in R that takes another function as argument: f <- function(g, ...) { #g is expected to be a function } I want to see if there is a way to implement "f" in C and calling it from R using ".C" interface. I know that I can use function pointers for my C implementation, but I imagine it's going to be nearly impossible to pass a function from R to C. Are

Hi Simon, Widespread errors would have caught my earlier as the way that code is using only one initialization of the embedded R, is used quite a bit, and is covered by quite a few unit tests. This is the only situation I am aware of in which an error occurs. What is a "correct context", or initial context, the code should from ? Searching for "context" in the R-exts manual

Dear r-devel folks, [if this is more appropriate for r-pkg-devel please let me know and I'll repost it over there ...] I'm writing to ask for help with some R/C++ integration idioms that are used in a package I'm maintaining, that are unfamilar to me, and that are now being flagged as problematic by Tomas Kalibera's 'rchk' machinery (https://github.com/kalibera/rchk);

Hello! I (try to) convert the external R header files to Pascal (Delphi). At one place I stumbled over a macro that uses a method that is not declared in a LGPL header file: In Rinternals.h: #define error_return(msg) { Rf_error(msg); return R_NilValue; } #define errorcall_return(cl,msg){ Rf_errorcall(cl, msg); return R_NilValue; } ~~~~~~~~

Hello, I am running a functional Xen 4.0 platform. The objective is the project I am currently running is to replace 4 VMWare ESX by 4 Xen 4.0 hypervisors. I have been able to reproduce all the core VMWare features in Xen (but better of course =D) except memory overcommitment. I know this feature has been included since Xen 3.3 but I have found almost no information about it. When I try to

Thanks, that's really useful. One more question for you, or someone else here: const ArrayXd glmLink::linkFun(const ArrayXd& mu) const { return as<ArrayXd>(::Rf_eval(::Rf_lang2(as<SEXP>(d_linkFun), as<SEXP>(Rcpp::NumericVector(mu.data(), mu.data() + mu.size())) ), d_rho); } I guess I need that to read

Please note that this is documented in ?trace. "fun" is matched to what, it is a _name_ of the function to be traced, which is traced in the top-level environment. I don't know why it was designed this way, but it is documented in detail, and hence the expected behavior. Debugging is often, and also in R, implemented in the core. Tracing is implemented on top without specific

Hello, I am a rather new user to OpenSolaris and I have been loving every minute of it. I have spent quite a lot of time looking around for bandwidth management features and Project Crossbow is just amazing. It is truly amazing compared to what Linux has to offer. I would like to use flowadm to do some bandwidth management on a tun interface. The problem is that it is not recognized by the dladm

Hello, I am experimenting with Snort and other IDS and I would like to use Xen for these tests. This would require me to use port mirroring to sent a bunch of packets to a NIC located on my Xen machine. I don''t really know how Xen networking works, but is it possible to give a domU direct access to a NIC ? Or at least give it enough access so that it can see packets that are not for the

Trace adds something to the body of the function, so it does make sense that it doesn't. Whether traced functions still technically meet the definition of standard s3 generic or not is, I suppose, up for debate, but I would say that they should, I think. As before, if desired I can work on a patch for this if desired, or someone on R-core can just take care of it if that is easier. Best, ~G
