(1) It seems to me that, generally, in R it is not possible to overload functions. Is that right? (2) Assuming that the above is true, or partially true, is there any extra packages to handle overloading in R? (3) Assuming (1) is TRUE and (2) is FALSE, can anyone provide some advice on developing some function that understand what the arguments are and then calls the right overloaded

I'm just curious if anyone else has had problems with this configuration. I added the CRAN repository to apt and installed 2.5.0 with apt-get. I then did an install.packages("Rmpi") on cluster nodes. Rmpi loads and lamhosts() shows the nodes, but mpi.spawn.Rslaves() fails (something to do with temp files?). Rmpi works fine with the Edgy-native version of R (2.3.x) and installing

Hi, Is there any parser generator like www.antlr.org? Moreover, how does simple code assistance work currently in R? By 'simple code assistance' I meant things like: Object$M<TAB> --> Object$Method

I have a use case where I would like to create an SEXP around an existing buffer that is managed by R, thus avoiding a copy operation. If I have something like: void *p = (void*) RAW(PROTECT(Rf_allocVector(RAWSXP, n))); ... additional maniupulation ... SEXP x = somefunc(SXPTYPE, n, p); // ???? Is there a "placement" constructor available? (I have arranged for the corresponding

Does anybody have any issues with the AJAX code inside rails? Whenever i use any sites i have built, or even external sites (such as basecamphq) my internal security device blocks access to the Ajax piece with a 400 Bad Request ( i scoured the net for other ajax examples and no isses anywhere else). I think there is something in the AJAX code of rails that is not implemented correctly. Has

Hello, I've been trying every now and then to find a cross operating system solution that would let me access PostgreSQL (and PostGIS) from R, or to access R from PostgreSQL. I know of pl/r, which accomplishes the latter, but has yet to be successfully ported to Windows. Similarly, I've tried to use Rdbi and DBI, but I haven't had luck with those on Windows either for connecting to

Hi, This question seems to be old, however I am asking it from a different point of view. R introduces itself as a 'statistical' language and environment. There are many discussions about comparing R to MATLAB or mathematica (or other similar software). It seems to me that these other software have a broader range of applications. For example, in Mathematica one can solve a partial

Last week I managed to automatically wrap over 600 C++ classes into R in less than 24 hours. It was not because I am an expert in R programming, it was simply because I wrapped the classes as S3. Not only the wrapping process was easy, but also installation process and loading the final library was fast too. Now I am also trying to do the wrapping into the 'modern' S4 classes. This

When dealing with object holding pointers that are only valid during a single session, it would be convenient to exclude them from being saved with the session image. (I am assuming that `quit` calls `save.image` before quitting or is it internal?) Currently they are saved with the pointer converted to NULL. Its a bit surprising for users not realizing the object is no longer valid. My thought is

I know there is some integration between Grass and R available, but has anyone produced a link between R and MFWorks. I am considering Buying MFWorks (Windows) and it would be useful to know if anyone has written such a link.
