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? 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.
Just a nitpick: Nothing in the GPL prevents you from charging someone
for your changes. It is often pointless, because when you deliver them,
you are also obligated to deliver the source code and the right to
redistribute everything. However, if someone really wants a new
feature in Linux or R, they could hire you to produce it, and it is
perfectly legal for you to charge them for the changes.

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.
