[R] calling R from C or C++

[herodote@oreka.com]

hi all

You should look into the "tests" directory (download the source package extract it and you'll have the tests directory)

there are some exemples on how to embedded R into C.

I've got the same trouble, here nobody want to do that, and i don't know why...

Just get the Magic Wand from the Harry Potter books; that way you get the
