The sharing objects thing seems like it would be fraught with errors and mismatches. R has a fundamentally different structuring than Python. From factors to numerics, and vectors.
If you can find an error in our implementation I would be happy to hear about it (ideally file an issue on github).
I am not an expert in R and I don't expect autotranslation to cover every case, but I think what we have is useful,
and I look forward to continuing to improve it based on community feedback.
