new_data_frame() constructs a new data frame from an existing list. It is
meant to be performant, and does not check the inputs for correctness in any
way. It is only safe to use after a call to
df_list(), which collects and
validates the columns used to construct the data frame.
new_data_frame(x = list(), n = NULL, ..., class = NULL)
A named list of equal-length vectors. The lengths are not checked; it is responsibility of the caller to make sure they are equal.
Number of rows. If
Additional arguments for creating subclasses.
df_list() for a way to safely construct a data frame's underlying
data structure from individual columns. This can be used to create a
named list for further use by
new_data_frame(list(x = 1:10, y = 10:1))
