It seems unlink doesn't work with wildcards in 2.5.0. I've tried R-2.5.0 under gnu/linux from source and the Mac binary from att research. Example: > dir() [1] "bgx.Rnw" "bgx.pdf" "run.1" > unlink("run.*",recursive=T) > dir() [1] "bgx.Rnw" "bgx.pdf" "run.1" > unlink("run.1",recursive=T)

Hello, The use of .Call and the like all depend on loading shared libraries and registering routines from it. Also, .Primitive and .Internal depend on routines being registered in the R binary. And applications that embed R can override routines declared in Rinterfac.h, but is there a way for an application embedding R to register other routines defined in the application without loading a

Hello, I need a bit of handholding with R, specifically, with writing packages for it. I'm a systems programmer, and am, on the request of several users of our software, working on generating R interfaces. For starters, I've written the following R function (which compiles): SEXP myincr(SEXP Rinput) { // Returns input integer incremented by one int input; SEXP returner; PROTECT(Rinput =

Dear list, I am trying to implement a publish-subscribe mechanism in for an embedded R interpreter. But somehow my registered closures seem to get collected by the GC, even though I have protected them. I have reducted my code to the following sample. Sorry if it is a little verbose. The first couple of call of calls still work, but at some point one of the callbacks (callback1 in my

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

Thanks a lot for your answer Jeroen! I should have mentioned that I had actually only checked with the win-builder, as I did not have R-devel installed on my computer. But based on your answer I installed R-devel locally on a Linux-server (Redhat), and the package could be checked without the NOTE. So you might be right that this is a windows issue. However, another package that I am maintaining

Dear list, I am trying to update a package to pass the CRAN-checks. But I am struggling with the following note: File 'psgp/libs/i386/psgp.dll': Found no calls to: 'R_registerRoutines', 'R_useDynamicSymbols' File 'psgp/libs/x64/psgp.dll': Found no calls to: 'R_registerRoutines', 'R_useDynamicSymbols' It is good practice to register native

Dear all, R on Macports relies on GCC 4.3 to build packages. I find that packages with shared objects that use C++ streams crash R if they're compiled using Macports' gcc43, but work fine if compiled in exactly the same way using Apple-supplied GCC 4.2. Has anyone here had the same issue/know what is causing this problem? Thanks, Ernest

Hi, R 2.5.0 isn't auto-completing paths properly as it used to. E.g. suppose I have: > dir("CEL/choe") [1] "chipC-rep1.CEL" "chipC-rep2.CEL" "chipC-rep3.CEL" "chipS-rep1.CEL" [5] "chipS-rep2.CEL" "chipS-rep3.CEL" Now if I do: ReadAffy("CEL/choe/ch<tab> # => ReadAffy("CEL/choe/chip

Hi all, I have some C++ code that I call from my package. In my main C++ loop, I check for user interrupts and return to the R shell after ensuring I've deallocated memory appropriately. This works fine when the code is compiled with gcc+openmp and with icc without openmp, but when I compile with icc and use openmp, the entire R session is immediately terminated when I hit ctrl-C. This

Dear all, I have wrapped a C++ function in an R package. I allocate/deallocate memory using C++ 'new' and 'delete'. In order to allow user interrupts without memory leaks I've moved all the delete statements required after an interrupt to a separate C++ function freeMemory(), which is called using on.exit() just before the .C() call. I am concerned about the

Why is it that R places CFLAGS after PKG_CFLAGS and not before when compiling a package (e.g. through R CMD build pkg)? This can be problematic if, for instance, you want to use -O3, but -O2 is in R_HOME/etc/Makeconf. If -O2 (in CFLAGS) appears after -O3 (in PKG_CFLAGS), you are left with what you didn't want: -O2. In R-exts, it says that "Flags which are set in file etc/Makeconf

Hi, Who should I ask about my package Rigroup_0.83 being moved to Archive status on CRAN and no longer available via install.package? I have no problems with the move if this was simply because of low demand. However, if there was a build issue with the newest releases that caused problems, I would be happy to address it. I'll just ask my students to install it from my own locally hosted

I am writing bindings to the neural network simulator SNNS. At present I have used only .C interface, now I'm studying .Call interface. I have adapted the example from page 77 of r-exts.pdf, however, it crashes R. I use MingW as recommended by Duncan Murdoch. Please, tell me what I am missing. The code is below. Thank you. SEXP snns_getVersion(void) {SEXP version; char *v;

The R_registerRoutines C function allows the number of parameters to a .Call function to be registered. For example, the tools package function md5sum() calls "Rmd5", which has been registered to require just one parameter. But if it is called with the wrong number of parameters, only the first error gets caught: > library(tools) >

I have a use case with tcltk-package where I need to repeatedly call Tcl/Tk functions very quickly. For such purpose, the standard R-interface turned out to be too slow, and better option has been to call package's C-function dotTcl directly from my own C-code. Before R 4.4.0 it was possible to use getNativeSymbolInfo("dotTcl","tcltk")$address (or

Dear all, I have a code chunk in my Rnw file that, when executed, outputs carriage return characters ('\r') to inform on the progress (e.g. "sweep 4 of 1024\r"). But Sweave interprets this as a newline character, and therefore I get countless pages of output in my vignette where I only really want one line. Any ideas? Thanks E

tempdir() on windows returns the path using "\\" as file separator. But .Platform$file.sep returns "/". As a result, you get inconsistencies like: > file.path(tempdir(), "foo") [1] "C:\\WINDOWS\\Temp\\RtmpYEIXrb/foo" # Mix of \\ and / I'm not sure if this can cause problems but I thought I'd let you know just in case.

R-helpers, Is there an easy way to call an external (C) program using .C or .Call without including the code in a package. I know how to do it using system(), but that doesn't seem to be a permanent or portable solution. Initially I tried: .Call('filepath.to.c.function', arg1) and got this error: Error in .Call("filepath.to.c.function", "arg1", :

Hello folks, I'm embarking on a project to embed R into the Apache web server, and I'd like your help. Currently, I'm looking for a way for R code to call back into a shared library from which the R shared library was loaded. Essentially, apache starts and loads mod_R.so which runs an initialization routine which calls Rf_initEmbeddedR() and the following code: /* override to
