Folks, this description is a bit cryptic, can somebody explain what label_from_df does, thank u
what is self.xtra?
label_from_df
(cols
:IntsOrStrs
=1
,kwargs
)
Label self.items
from the values in cols
in self.xtra
.
Warning: This method only works with data objects created with either from_csv
or from_df
methods.
