% symbol in .Rd files?
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

Problem installing gdb into Rtools42
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.

Resolving functions using R's namespace mechanism can double runtime
It appears that the runtime for an R script can more than double if a few references to a function foo() are replaced by more explict references of the form pkgname::foo(). The more explicit references are of course required when two loaded packages define the same function. I can understand why use of this mechanism is not free in an interpreted environment like R, but the cost seems rather

Rcpp, best method for linking to
Dear all, After a bit of reading I came across the Rcpp example package. There are a few classes that I would like to use and I am not sure how best to include them in my own package. Is it best to compile it as an independent library and link to it? Or is there some way to `require` it for my own package? Re-write using the code as an example (unsure how best to do this at this moment, as

Problem installing gdb into Rtools42
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

GPL and R Community Policies (Rcpp)
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

Telling Windows how to find DLL's from R?
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). Thanks, Dominick [[alternative HTML version

Rcpp: Clarifying the meaning of GPL?
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

Why no race condition when returning UNPROTECT-ed memory from C?
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

Memory allocation in C/C++ vs R?
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

Problem installing gdb into Rtools42
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...

RUnit bug?
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

Avoiding name clashes: opinion on best practice naming conventions
Dear List, I'm trying to figure out some best practice way with respect to the naming conventions when building own packages. I'd like to minimize the risk of choosing function names that might interfere with those of other packages (both available ones and those yet to come). I came up with following alternatives 1.

Windows Vista Issues
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
