Can I butt in for a moment and ask why we'd even want q() not to exit?
There is (unfortunately) no way to create and destroy multiple R
sessions, because R doesn't have such a capability. Even if there
were, I don't see what q() would have to do with it -- the right API
for creating and destroying sessions would be more like
my_r = rpy2.R()
# ... do stuff with my_r ...
del my_r
or whatever. There is an rpy2.rinterface.endEmbeddedR() which tries to
clean up the R data structures without exiting the process; the only
problem is that you can't re-initialize R afterwards.
q() is a function for exiting the process, just like sys._exit or the
C exit() function or whatever. If you call any of them the process
will exit. This makes sense if you think about it...
If you're just worried about users accidentally calling q() and being
surprised by the results, it'd be easier to just say
r('q <- function(...) { "Don't press the red button!" }')
or whatever at startup.
In conclusion, I don't get it :-)
