Re: [Rd] destructor for S4 class objects in analogy to C++

if you are using external pointers, then R allows you to set a finalizer function to be called on the pointer. http://cran.r-project.org/doc/manuals/R-exts.html#External-pointers-and-weak-references see examples in RODBC package. and here too: see the "connFinalizer" function http://github.com/a

[Rd] destructor for S4 class objects in analogy to C++

Hi all, I'm wondering if there is a way to define a destructor function (to free memory) for S4 class objects in analogy to C++? rm() combined with gc() does not seem to be a good idea (Chambers, 2008). So could it be done on the C/C++ level or is it even already available in the "internals"? Man

[Rd] Building a package with BLAS under Windows

Hi everybody: I am writing a package that includes C code that uses the BLAS library. My Makevars looks like PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS). If I check and build the package under Linux on my own computer everything works fine. However, if I submit the package to win-builder I

[Rd] building source package in R run within Emacs under Windows.

Did you try starting up R-2.8.1 and checking the result of file.access(lib, 2) on that very same directory where R-2.9.1 gives an incorrect indication? If that gives the correct answer, then, look for changes in the file.access code. -- Tony Plate Kevin R. Coombes wrote: Hi, The problem al

Re: [Rd] Rcmd check fails on Windows Samba network path in R 2.9.1

Hi, The problem almost certainly has something to do with Samba. We also have a NetApp file system, and copying the package source to that drive and running Rcmd check from Windows works just fine. When running the commands from an interactive R session, file_test returns TRUE and file.acce
