[Pharo-users] Re: Introducing new feature dataTypes for the PolyMath/DataFrame project

Hi Balaji,

Thanks for pointing this out. You are right with how the data types are calculated, similar to collection >> commonSuperClass. But this time, it is calculated only during the creation of DataFrame once and for all.

That sounds good.

A nil value, or a Series of nil values yields UndefinedObject as its super class. There was an error with the dataset used on that example blog post. I have corrected it now.

OK, that explains my confusion. Cheers, Konrad.
