Apply a function to each element of a vector or list
The map functions transform their input by applying a function to each element and returning a list/vector/data.table.
map.() returns a list
_lgl.(), _int.(), _dbl.(),_chr.(), _df.() variants return their specified type
_dfr.() & _dfc.() Return all data frame results combined utilizing row or column binding
map.(.x, .f, ...) map_lgl.(.x, .f, ...) map_int.(.x, .f, ...) map_dbl.(.x, .f, ...) map_chr.(.x, .f, ...) map_dfc.(.x, .f, ...) map_dfr.(.x, .f, ..., .id = NULL) map_df.(.x, .f, ..., .id = NULL) walk.(.x, .f, ...) map2.(.x, .y, .f, ...) map2_lgl.(.x, .y, .f, ...) map2_int.(.x, .y, .f, ...) map2_dbl.(.x, .y, .f, ...) map2_chr.(.x, .y, .f, ...) map2_dfc.(.x, .y, .f, ...) map2_dfr.(.x, .y, .f, ..., .id = NULL) map2_df.(.x, .y, .f, ..., .id = NULL)
