Ok, thanks for that. I though that, since R in under GPL-v2, I
can only release my code under GPL-v2 because the code is written

Did you include someone else's GPL-vx code (possibly modified by
you) as part of your code in a way that someone could claim that
your code does NOT have a useful functionality and independent
existence without that?
Nope. Nevertheless my code would not have a functionality without R,
hence I feel GPL v2, the same R is under, is appropiate for my
package.
It could presumably run unchanged under S-Plus, and the same
license could probably be claimed to apply to a version that ran under
Matlab. Either of these could arguably give it an independent
existence, even if that independent existence were never exercised.
However, as I said, I'm not an attorney.

I'm not an attorney, but I have read the GPL and discussed it with
attorneys, and it's my understanding that the definition of
"derivative work" encompasses essentially what I just described.
Another example: According to the Wikipedia article on Linux, the
(first) GPL was written for the GNU Linux project. In that
context, you can NOT charge someone for Linux nor for any
modification of it you may make, because such modifications would
make it a derivative work. However, if you can run your own code
written in whatever language under Linux, because presumably your
code has an existence independent of Linux and could theoretically
run (with modifications) on some other operating system.
Hope this helps. Spencer
On uploading the new version (a matter of days), I will specify
the GPL version.
