I just tried it myself and couldn't understand how it works ... I got the same error as you, but even more, after two or three refreshes on the page, I get:
File "/var/tmp/modpython/mptest.py", line 2, in <module> import rpy File "/usr/lib/python2.5/site-packages/rpy.py", line 346, in <module> r = R() File "/usr/lib/python2.5/site-packages/rpy.py", line 286, in __init__ _rpy.r_init(HAS_NUMERIC); RuntimeError: Only one R object may be instantiated per session So I guess you can't plainly import rpy from within modpython due to the way sessions are managed. About the get problem I have no clue either...
