Conda install screwed up my environment. Can I undo it?

I tried installing rpy2 so that I could work with R files (.rda) using conda install -c r rpy2, and it totally screwed up my environment.

For example:

1) When I try importing pandas, I get this error: AttributeError: module 'pandas' has no attribute 'core'

2) When I try importing matplotlib, I get this error: AttributeError: module 'matplotlib' has no attribute 'artist'

I wasn't having these issues before I installed this package. Is there a way to undo what I just did - as if I never installed it in the first place?

You can "roll back" to a previous revision. First, run: 

conda list --revisions

You will get a list of revisions with their revision number. Then, look at the second-to-last revision and take note of its number. To revert to this revision, run:

conda install --revision N

where N is the revision number.
