similar to: Problem with Rboolean in c++ code

(Tried this query on r-help with no luck, maybe someone here can help?) I would like to call the 'RFinalizerEx' function that appears in Rinternals.h using ".Call". It worked for me in the past, but now I get an error message something like: 'call function name not in call table'. I'm using the 1.6.1 rpm from CRAN. Anyone know what's going on? Thanks. Tim --

Hello, I'm evaluating this expression expression({ for(x in 1:5){ .Call('rh_status','x') }}) a million times from a program with R embedded in it.

Hi, I have been trying to install the Matrix package on R running in Linux (Fedora). But, I get the following error message (at the bottom). I am logged in as the root user.

Dear All I'm currently developing a package for R (1.9.0) on Win32, with C++ source code. Having followed the instructions in readme.packages, my code compiles fine with R CMD SHLIB (as well as R CMD check) ... until I start using the internal R functions. (Interesting: Rprintf seems to be the exception.) For instance, the following code compiles fine: #include <R.h> #include

Dear list, The utility "R_has_slot" mentioned in the file NEWS ("Experimental R_has_slot() utility supplementing R_do_slot()") appears to be missing from a fresh checkout of the development branch. $ svn up At revision 44759. $ grep -i has_slot `find include -name '*.h'` $ grep -i _slot `find include -name '*.h'` include/Rdefines.h:#define GET_SLOT(x, what)

Dear Group, I'm trying to build a set of new graphic device drivers. I use the devNull example a a beginning point: $ R CMD SHLIB devNull.c gcc -shared -L/usr/local/lib -o devNull.so devNull.o (everything works OK) $ R CMD SHLIB devNull.cpp g++ -shared -L/usr/local/lib -o devNull.so devNull.o (everything works OK) The difficulties start when trying to compile manually. I compile the

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

Hello list, I've been working on a package of my own. It works fine on the 32bit linux machines that I've tested it on. Someone using 64bit ubuntu wanted to try it, and surprising segfaults happened. My test code results in no segfault, errors, or leaks from my calls when run under valgrind (I recompiled R with the level 2 valgrind instruments). R and packages are compiled from source,

Hi folks, I apologise if this is in the documentation somewhere, but I can't seem to find it. I also did a search of CRAN without any success. I'm using R-1.8.1 (pre-compiled) on Windows 2000 with Rtools and mingw 2.0.0 (which includes gcc/g++ 3.2). I'm trying to link some C++ code from another application to R using the .Call interface and am experiencing some problems. I was

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

Looking for more ways to speed up R, I've found that large improvements are possible in the speed of "sum" and "prod" for long real vectors. Here is a little test with R version 2.11.1 on an Intel Linux system > a <- seq(0,1,length=1000) > system.time({for (i in 1:1000000) b <- sum(a)}) user system elapsed 4.800 0.010 4.817 > system.time({for (i

Hello, The current xfig device lacks the functionality to set the textspecial flag and use the defaultfont in xfig. This is necessary when you want to export to xfig and use interpreted text (e.g., $ \frac{1}{e}$ gets interpreted by latex). The attached patch adds this functionality. Why would you like to do this? - Use math in labels (e.g., name your variables $r_{xy}$, do a

Hello, I try to write parts of my code in C to accelerate the for-loops. But basic operations I want to do in R (e.g. start cluster). My R code looks something like this: library(Rmpi) mpi.spawn.Rslaves() mpi.remote.exec(....) dyn.load("test.so") erg <- .Call("test", ....) .... mpi.close.Rslaves() mpi.quit() And my C function looks something like this: #include

Hello everyone, I try to write a c++ code which calls embedded R and uses some of R internal functions. What I read is just lots of macro names defined in the Rinternals.h or Rdefines like R_Parse, Rf_install and so on. But where can I get the detailed information about the parameters of these macro? For example, what about the parameters of SEXP R_ParseVector(SEXP, int, ParseStatus *)?

A package that I develop (xcms) sometimes needs to read and process vectors several hundreds of megabytes in size. (They only represent parts of a large data sets which can approach nearly 100GB.) Unfortunately, R sometimes hits the 2GB memory limit of Win32. To help cut the memory footprint in half, I'm implementing a "float" class as a subclass of "raw". Because
