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

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

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.

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

rgl/webGL complains about Javascript, even in recent online docs?
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.

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

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

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

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...

NAMESPACE
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

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.

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.

have permission to write to Program Files/R/R-version/library. Apparently
the install process has already been modified to give
