...e real issue was not the behavior but that it was not documented or consistent. I've lived by the mantra since that you can never trust a pointer in R code. User must always check for NULL. I just wrote my own functions mkXXX_safe that wrap the internals and check the pointer. THK http://www.keittlab.org/ [[alternative HTML version deleted]]

...what I need. I was trying out a little experiment, but I think its not possible right now because the length of an R vector is identical to the buffer length.

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

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.

Not necessarily. A char* of

(1) Assume we have some automatic C++ wrapper which , briefly, reads the C++ files and generates some R files in which the equivalent of the C++ classes are reconstructed. (2) As the OO design of R is different to that of C++, some isses exist when creating an interface between these two systems. (I said these two are 'different', I didn't say which one is better or which one is

An example from the sos package: Its DESCRIPTION file says Author: Spencer Graves, Sundar Dorai-Raj, and Romain Francois. However, the package includes a findFn function, whose help file includes an Author(s) section, which reads, "Spencer Graves, Sundar Dorai-Raj, Romain Francois. Duncan Murdoch suggested the "???" alias for "findFn" and contributed the code for
