mutate to substring doesn't work #84

Closed dbuzolin-nfl closed 5 years ago

dbuzolin-nfl commented 5 years ago

I am trying to extract a date portion from datetime via mutating into a substring and resulting dataframe still prints whole datetime field: df >>= mask(X["Item Type"] != 'Application') >> mutate(transaction_date = X["Transaction Time"][0:10]) Resulting df.transaction_date prints full string, ex: 2019-02-10 19:21:45 PST

I see this is achieved via @make_symbolic functions
