Hi, apparently I sent my question about using R and C++ to the wrong list, ironically seeing as that list was called Rcpp. Anyway, I was directed to post my question here. To summarize my current question, I have found two commands that I want to be able to put into a package. The commands are 'R CMD SHLIB X.cc X_main.cc' and

Duncan, I don't know what we want, but it is not a simple matter of documenting what .dynLibs currently does. What I see as bugs are 1) the inconsistent names and types of the components returned by .dynLibs(). 2) the inconsistent inclusion or not of R_X11 in the list returned by .dynLibs(). 3) the inclusion of static info (base) by library.dynam(). 4) including loadable modules s...

...ession to load shared libraries. This vector is returned as 'invisible', unless the 'chname' argument is missing. which is clearly no longer true. I don't see why we want loaded modules in there that have nothing to do with packages, or even non-modules. At that point .dynLibs() gave $base DLL name: base Filename: base Dynamic lookup: FALSE $stats DLL name: stats Filename: /usr/local/lib/R/library/stats/libs/stats.so Dynamic lookup: TRUE [[3]] [1] "methods" which seems useless for '.dynLibs' is used for getting or setting the packages that hav...

Good question Rolf. Rui, thanks for pointing out dyn.unload. When I started using Rcpp a couple of years ago I got burned by stale .so enough times that I adopted a policy of recompile-then-start new R session. My workflow does not include Rolf's "brazillion" repeats, so the overhead of this approach has not been too painful. The documentation for dyn.unload (via ?dyn.unload)

...uce multiple evaluators in the future, lots of things will "challenge" the current semantics and many of them will be desirable. One of these potential changes is the use of multiple concurrent versions of a package.

...age, and this strategy won't work for them. I'm aware that the NAMESPACE file will have an entry like this: useDynLib(libname) but I don't know how to access this information from within R. Is this possible? Another strategy I've looked at is to get all the directories listed by .dynLibs() and picking out those that contain the path of the package, but I'd prefer not to do it this way if possible, since it seems like a bit of a hack. For example, this code will load bitops, then unload the shared library and unload the package. library(bitops) # Show what's loaded .dynLib...

Dear R .Call() insiders, Can someone enlighten me how to properly finalize external pointers in C code (R-2.5.1 win)? What is the relation between R_ClearExternalPtr and the finalizer set in R_RegisterCFinalizer? I succeeded registering a finalizer that works when an R object containing an external pointer is garbage collected. However, I have some difficulties figuring out how to do that in an

Dear r-bugs, I'm having problems loading the 'grid' package when it has been detached earlier in the same session: > library(grid) > detach("package:grid") > library(grid) Error in .Call("L_initGrid", PACKAGE = "grid") : .Call function name not in load table Error in library(grid) : .First.lib failed This bug was mentioned on r-help

Hello! I am working with LLVM project to compile for specific processor (xPEC-processor from NetX chip, http://hilscher.com/ ). I have done support of this target successfully! Assembler code can be emitted with debug information. LLVM - great!) But now I am looking for generation of machine code for my target. I have seen, that "llc" has option "-filetype". It has

Dear R developers, The trace of the hat matrix H~(n,n) is computed as follows: tr(H) = tr(BS^-1B') = tr(S^-1B'B) := tr(X) = sum(diag(X)) with B~(n,p), S~(p,p). Since p is of the order 10^3 but S is sparse I would like to employ Taucs linear solver ( http://www.tau.ac.il/~stoledo/taucs/ ) on SX = B'B. (Further improvement by implying a looping over i=1,...,p, calling

In the "Writing R Extensions" manual appears this example, to get access to C++ function using the R commands: R> dyn.load(paste("X", .Platform$dynlib.ext, sep = "")) constructor Y R> .C("X_main") constructor X destructor X list() That gives me access to the function "X_main", but how to get access to methods and properties

I am working on a SLES 10 cluster with R available on it. To better use my resources, I want to use Rmpi, but I am having a difficult time installing it. I have set the $R_LIBS variable correctly. The MPI libraries are available through the PGI compiler, but this R instance was compiled with GCC. The Rmpi package can be compiled and installed with %R CMD INSTALL Rmpi_0.5-5.tar.gz

Hi all, I have written a script in R that simulates genetically informative data - it is posted on my website and available to the public. This is my first time to write a script for use by others and am learning that it isn't as easy as it seems. To the issue. My script runs fine on my machine and on a server I have access to, but a user has written me saying that it crashes the first time
