vec_map_dfr: Apply a function to each element of a vector and combine into...

In DavisVaughan/vcturrrs: Combining the Iteration of 'purrr' With the Type Stability of 'vctrs'

Description

Unlike map_dfr(), vec_map_dfr() treats vectors as 1 row data frames.

Usage

vec_map_dfr(.x, .f, ...)

vec_map_dfc(.x, .f, ...)

Arguments

.x	A list or atomic vector.
.f	A function, formula, or vector (not necessarily atomic). If a function, it is used as is. If a formula, e.g. ~ .x + 2, it is converted to a function. There are three ways to refer to the arguments: For a single argument function, use . For a two argument function, use .x and .y For more arguments, use ..1, ..2, ..3 etc This syntax allows you to create very compact anonymous functions. If character vector, numeric vector, or list, it is converted to an extractor function. Character vectors index by name and numeric vectors index by position; use a list to index by position and name at different levels. If a component is not present, the value of .default will be returned.
...	Additional arguments passed on to the mapped function.

Examples

library(purrr)

x <- stats::setNames(1:5, 1:5)

map_dfr(x, ~ .x)

vec_map_dfr(x, ~ .x)
