Hi,
Pickling/unpickling of R objects did not change between the 2.1.x and
2.2.x series, but the declaration of import path might have (I vaguely
remember having to work something our for Python 2.7 and/or Python 3).
You best bet currently might be to:
-re-install 2.1.9
- save the R objects using R's own serialization mechanism ("save()")
into a file
- re-re-install 2.2.1
- load the R objects using R's unserialization ("load()")
- pickle the objects loaded/
Best,
L.

Hi,
I recently upgraded from rpy 2.1.9 to rpy 2.2.1, on a linux x86 system.
I had a number of r objects that were pickled under the old version,
and after I upgraded, I am no longer able to unpickle them. I get the
error message "ImportError: No module named rinterface".
I am able to pickle and unpickle fine under the new version without a
problem.
Is there a way to recover the files saved under the old version?
Thanks for any help.
