There appears to be a bug in RUnit. Given a testsuite testsuite.math, say, when I run: runTestSuite(testsuite.math) this works fine, provided there are no extraneous files in the unit test subdirectory. But if there are any Emacs temp files (with names that end with '~') then runTestSuite gets confused and tries to run functions from the temp files as well. [[alternative HTML version

All, I have some data that I need to be able to see across the application. For J2EE people out there, I need something that I want to have available in the "application scope" of my app. What is the best way to handle this? I''m trying to access a class variable that I created in my controller from my view (to no avail). Create a class variable in my helper class and use

This post asks members of the R community, users and developers, to comment on issues related to the GNU Public License and R community policies more generally. The GPL says very little about protecting the the rights of original contributors by not disseminating misleading information about them. Indeed, for pragmatic reasons it effectively assumes that original authors have no rights regarding

Is it possible to set Windows' search path from within R, or to tell Windows how to find a DLL in some other way from R? Specifically, if a package DLL depends on another DLL the normal requirement is that the second DLL be in the search path so Windows can find it (there are other tricks, but they apply at the Windows level, not at the R level).

On second thought, there is a lot of metapramming code in Rcpp that runs before main, so I was wrong to say nothing can happen before main() is called. Strategically placed print statements may be the best strategy.

I wrote the Rcpp library and the RcppTemplate package to make it easier for developers to contribute packages to the R community. In addition to providing detailed documentation on package creation it provides a clean object mapping between R anc C++ that helps developers to implement packages that benefit from the performance of C++ and the flexibility of R. The package named 'Rcpp' was

FYI, one platform where I have not been able to get interactive rgl working is iOS 8. iOS 8 is supposed to support WebGL, and Javascript is enabled.

Consider the C (or C++) code called from the .Call interface: SEXP foo() { SEXP *p = PROTECT(allocVector(REALSXP, 10)); ... UNPROTECT(1); return p; } Why is there no danger that the allocated memory will be garbage collected after the UNPROTECT, but before the return of p? I have used code like this for some time and have never had a problem, but I'm not sure if/why it is guaranteed

Hello, I am encountering problems when there is a '%' character in package .Rd files. More precisely, CRAN is having problems with these characters when running check, whereas I am not seeing any problems under Linux and Windows. I did see these problems, and found that escaping the %'s fixes the problem in my testing, but apparently this does not fix the problem when check is run at

Thanks for the detailed feedback Tomas, I ran the command 'pacman -Syuu' again, just to be sure, and this time it says "there is nothing to do." It appears that gdb is working. I was spooked by the diagnostics that you say is a known (not serious) issue. My mistake was not setting a breakpoint on main, so I confused problems with gdb with problems with the program I'm

The R docs say that there are two methods that the C programmer can allocate memory, one where R automatically frees the memory on return from .C/.Call, and the other where the user takes responsibility for freeing the storage. Both methods involve using R-provided functions. What happens when the user uses the standard "new" allocator? What about when a C++ application uses STL and

Thanks, But this didn't work. It installs msys2 along with lots of other stuff, and gdb would not start as before (missing DLL's). Then I tried to run the command you suggested again, and there was a warning from the package manager about a cycle detected, but now gdb starts with the following messages...

Hello, I just tried to use NAMESPACE to prevent name conflicts between packages and it appears that once a name is exported it will clash with the same name if it is exported from another package, in particular, if that other package does not use NAMESPACE. Is there a way to "export" a name so that the current package user can see it, but other packages cannot see it? My working

Consider the R code: mat <- matrix(seq(1,20),4,5) is.matrix(mat) # gives TRUE is.vector(mat) # gives FALSE On the other hand, if mat is passed through the .Call interface the corresponding SEXP (call it smat) satisfies isMatrix(smat) // TRUE isVector(smat) // TRUE Consequently, you cannot distinguish matrices from vectors. Looking at the dim attribute of a vector doesn't help because

Hello, I am trying to call the BLAS Level1 function zdotc from R via a .C call like this: #include "R.h" #include "R_ext/BLAS.h" void testzdotc() { Rcomplex zx[3], zy[3], ret_val; zx[0].r = 1.0; zx[0].i = 0.0; zx[1].r = 2.0; zx[0].i = 0.0; zx[2].r = 3.0; zx[0].i = 0.0; zy[0].r = 1.0; zy[0].i = 0.0; zy[1].r = 2.0; zy[0].i = 0.0; zy[2].r = 3.0;

This is a repost of a simple question about Windows Vista and R (with answer), along with a heads-up on other Windows Vista issues that people may not be aware of and that may impact R development. 1. The standard package install process fails because the user does not have permission to write to Program Files/R/R-version/library. Apparently the install process has already been modified to give
