column.colsplit2df
- returns a dataframe with the paste2
column split into new columns.
lcolsplit2df
- returns a list of dataframes with the
paste2
column split into new columns.
colsplit2df
- Wrapper for colSplit
that returns a
dataframe.
lcolsplit2df
- Wrapper for colsplit2df
designed for qdap lists
that returns a list dataframes.
lcolsplit2df
is a convenience function that is less
flexible than colsplit2df
but operates on multiple
dataframes at once.
This will strip the class of the qdap object.
