new_data_frame {vctrs} | R Documentation |
A data.frame
data.frame()
is a list with "row.names" attribute. Each
element of the list must be named, and of the same length. These functions
help the base data.frame classes fit in to the vctrs type system by
providing constructors, coercion functions, and casting functions.
