slice_rows()
is equivalent to dplyr's
dplyr::group_by()
command but it takes a vector of
column names or positions instead of capturing column names with
special evaluation. unslice()
removes the slicing
attributes.
slice_rows(.d, .cols = NULL)unslice(.d)
A data frame to slice or unslice.
A character vector of column names or a numeric vector
of column positions. If NULL
, the slicing attributes are
removed.
A sliced or unsliced data frame.
