map
(Package: purrr) :
Apply a function to each element of a vector
map() returns the transformed input; walk() calls .f for its side-effect and returns the original input. map() returns a list or a data frame; map_lgl(), map_int(), map_dbl() and map_chr() return vectors of the corresponding type (or die trying); map_df() returns a data frame by row-binding the individual elements.

CranContrib
● Keywords:
● Alias: map, map_chr, map_dbl, map_df, map_int, map_lgl, walk

prepend
(Package: purrr) :
Prepend a vector
This is a companion to append() to help merging two lists or atomic vectors. prepend() is a clearer semantic signal than 'c()' that a vector is to be merged at the beginning of another, especially in a pipe chain.

slice_rows
(Package: purrr) :
Slice a data frame into groups of rows
slice_rows() is equivalent to dplyr's 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.

● Keywords:
● Alias: slice_rows, unslice
