lap: List apply functions

Function(s) that apply expressions to input data objects and return lists.

lap: Iterate over input and return list(s)

lap(.data, .f, ...)

`.data`	Input object–numeric, character, list, data frame, etc.–over which elements will be iterated. If matrix or data frame, each column will be treated as the elements which are to be iterated over.
`.f`	Function to apply to each element of input object. This can be written as a single function name e.g., `mean`, a formula-like function call where '.x' is assumed to be the iterated over element of input data e.g., `~ mean(.x)`, or an in-line function definition e.g., `function(x) mean(x)`.
`...`	Other values passed to function call.

A list


## return string list
lap(letters, ~ paste0(.x, "."))

## return list of columns
lap(mtcars[1:5, ], as.character)
