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

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

Hello, I submitted the package RcppTemplate to CRAN a couple of weeks ago but the Mac OS X binary has not appeared, and the person in charge of that process (Simon) suspects that the problem may be due to a "nested DESCRIPTION file" so that "Package:" becomes RcppTemplateRcppTemplate, or something like this. Can somebody explain what a nested DESCRIPTION file is so I can

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.

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.

Hello, After much tinkering I managed to build packages using the 64bit version of R with the help of hints from http://www.murdoch-sutherland.com/Rtools/ and http://www.stats.ox.ac.uk/~ripley/Win64/W64porting.html and R-admin Manual. But a hack was required, and this seems to be related to a comment about underscores at the end of the second reference above (but this comment is about FUTURE

New Rcpp versions 0.6.0 and 0.6.1 --------------------------------- The Rcpp package provides C++ classes that greatly facilitate interfacing C or C++ code in R packages using the .Call() interface provided by R. Rcpp provides matching C++ classes for a large number of basic R data types. Hence, a package author can keep his data in normal R data structure without having to worry about

Hello, When I try to install Rtools in the usual way into C:\Rtools on a new Windows 8.1 desktop it stalls near the beginning of the "Extracting files..." step. The Task Manager Status for the Setup app shows "Not responding" and it takes a long time to complete the installation, in spite of the fact that this is a fast machine (Intel i7) with 16 GB if RAM. There were no

Hi, I am trying to create an R interface for Dynare++ [1], a k-order solver for rational expectation models. I would like some advice on how to glue the C++ code to R. In C++, it works the following way: - a DynareModelEq object is initialized with the formulas, parses them and performs k-order symbolic expansions - the user calls a member of this object multiple times with parameter

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

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

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

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

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... Traceback (most recent call last): File "<string>", ine 3, in
