[R] how to call a C program from R function

[Martin Olivier]

Hi all,

I would like to call a C program from R function. I tried to use the 
.C() function
without success. I need a very simple example (such as the hello 
program) to understand
how it works. Could you give a  such example?
(I use the  1.7.1 Version of R with linux)

Does it work in the case of a C++ program instead of a C programm?

Best regards,
Olivier
