similar to: Alternative to .Internal(.dfltStop(msg, call))?

Does signalCondition() only work within try-catch blocks? I expected: testSignal <- function() { error <- simpleError("An error!") signalCondition(error) } to do the same thing as testStop <- function() { error <- simpleError("An error!") stop(error) } but testSignal returns NULL without throwing an error. Have I misunderstood something?

Hi, I have some surprising trouble installing the gputools package. This is a linux box running Fedora with an Nvidia GeForce GTX 260 card and R 2.12.1 I had gputools running on it for the past several months. Wanting to update to the newest version, I simply executed install.packages("gputools") from within R. This should mean that the problem isn't in the hardware or OS. Errors

Hi, I downloaded 2.8.1 and tried to compile it using gcc 3.4.6. (simple install, just ./configure, make, make check, make install) I found that it compiled and went through the tests fine. The foreign library, however, that seems to be segfaulting on me (see output below). I did see an old posting about a similar problem, but there was no resolution. Have other people experienced this at all?

Hello, I would like to establish top level condition handlers and restarts, so that I don't explicit calls to withCallingHandlers and withRestarts in many places: For example : > customError function( message ){ err <- simpleError( message ) class( err ) <- c( "customError", class( err) ) err } > withCallingHandlers( { signalCondition(customError(

Thanks for the report, but unfortunately I cannot reproduce on my system (either macOS nor Linux, from the command line) to debug. Did you run this in the command line version of R? I would not be surprised to see such a crash if executed from a multi-threaded application, say from some GUI or frontend that runs multiple threads, or from some other R session where a third party library

Hello, I want to use withCallingHandlers(expr, warning = function(w) { ....}), that is, to use a custom warning handler. I want this handler to replicate the behavior of the usual handler. I have problems with the mode 'options(warn = 0)' where the warnings are delayed, except if calling 'warning("message", immediate. = TRUE). Indeed, if my custom warning handler

This code actually happens to work for me on macOS, but I think in general you cannot rely on performing HTTP requests in fork clusters, i.e. with mclapply(). Fork clusters create worker processes by forking the R process and then _not_ executing another R binary. (Which is often convenient, because the new processes will inherit the memory image of the parent process.) Fork without exec is not

In current definition of function 'stopifnot' in stop.R in R 3.6.0 beta (https://svn.r-project.org/R/branches/R-3-6-branch/src/library/base/R/stop.R) or R devel (https://svn.r-project.org/R/trunk/src/library/base/R/stop.R), if 'exprs' is specified, cl[[1]] is quote(stopifnot) . To be more robust, quote(base::stopifnot) may be used instead. Also, in current definition of function

It's been a few days I cannot compile to get R-2.12.0 working at sparc Solaris 10. Seems the R software installation is OK, but the recommended package called Matrix stopped me, since I can finish the installation with the configure option -with-recommended-packages=no. I then run Ø Install.packages("Matrix") Then last few lines of output are the following, 28: tryCatch(expr,

Hello all, (Thank for your reply) I have a web-application in Apache Tomcat, when i start R in this application, I used packe RSJava Code ROmegahatInterpreter interp; String [] rargs = {"--no-save"}; REvaluator e; interp = new ROmegahatInterpreter ( ROmegahatInterpreter.fixArgs(rargs),false ); e =new REvaluator (); Errors ================ R version 2.10.1 (2009-12-14)

R Help List: Just curious if anyone has successfully built R on a SPARC platform running Sun Solaris 10 using the latest Sun Studio 12 set of compilers. If so, I would be interested in the compile flags that you used. I have tried several different builds of version 2.5.1, 2.6.0, and 2.6.1 using various different compile flags and I am able to compile and check, but for whatever reason, the

I am having difficulty installing the arm package and would be grateful if anyone could give some advice. I have updated my computer to a Mac OS X version 10.5.5 ( processor: 2 x 2.8 GHz Quad-Core Intel Xeon) and I have downloaded R version 2.8.0 I have downloaded the package arm, but when i try to install it, the following message is given in R: Loading required package: MASS Loading

I recently noticed a change between R-3.3.3 and R-3.4.0 in the definition of the R_CMethodDef struct. typedef struct { const char *name; DL_FUNC fun; int numArgs; - R_NativePrimitiveArgType *types; - R_NativeArgStyle *styles; - } R_CMethodDef; I suspect this is the reason that packages installed by R-3.4.0 and loaded into R-3.3.3 will crash the

Dear R List, I encountered a serious problem regarding the registration of ".C" when following the documentation "Writing R Extensions" that leads to a segmentation fault (tested on windows and mac os x). The registration mechanism for ".C" routines via R_registerRoutines and the R_CMethodDef structure has been enhanced recently with the addition of two fields, one

Dear list. Has anybody had any issues with ROracle, namely consistently leading to a segmentation fault? One of our oracle databases seems to have certain issues at the moment (do not know what exactly though) and if that one is queried ROracle definitely fails with a segmentation fault. Any ideas? Here is the trace and below is also a type of query that crashes it: *** caught segfault ***

Hi, I would like to bring up and old suggestion [http://tolstoy.newcastle.edu.au/R/devel/06/03/4512.html] of adding an exit condition, so that for instance it is possible to silently exit from scripts and Rd examples similar to return() for functions, e.g. \examples{ require("foo") || exit("Example will not run without the 'foo' package.") ... } I know this can be

I'm confused by the page documenting tryCatch and friends. I think it describes 3 separate mechanisms: tryCatch (in which control returns to the invoking tryCatch), withCallHandlers (in which control goes up to the calling handler/s but then continues from the point at which signalCondition() was invoked), and withRestarts (I can't tell where control ends up). For tryCatch the docs say
