Saving TearSheet as Variable

I have been toying around with the alphalens.tear library, and have found it very useful to be able to use functions such as  create_summary_tear_sheet and  create_information_tear_sheet  to view data about predictive power of certain factors.

However, I would like to be able to analyze these results in a more in-depth way than what the naked eye can accomplish. Therefore, I'd really like to be able to save the columns from my tearsheet into a variable (preferably a DataFrame) for further analysis.

My problem is that I can't quite seem to find out how to actually save this information. It seems to be pretty much not just read-only but read-only-when-created. This seems a little limited, so I'm sure this isn't true but I can't for the life of me find more information in the documentation about accessing the information in the tear sheets.

Any help would be so appreciated!
