vselect: Select vector with tidyselect functions

In kueckelj/confuns: Convenience Functions

Select vector with tidyselect functions

Description

A wrapper around the tidyselect functions that allows to use them not only on data.frames but on vectors as well.

Usage

vselect(input, ..., out.fail = base::character(0))

lselect(lst, ..., out.fail = base::list())

Arguments

input	A character vector or a factor.
...	Additional selection helpers from the tidyselect package that match names according to a given pattern.
out.fail	Output if no content remains after tidyselection has been tried.
lst	A named list. (Unnamed elements are discarded.)

Value

A subsetted version of the input.

Note

vselect() selects by element. lselect() selects by element name.

Examples

 library(datasets)
 library(confuns)

 vec <- c("apple", "banana", "pineapple", "tomato")

 vselect(vec, contains("apple") | ends_with("o"))

 lst <- list(a = mtcars, ab = iris, ac = cars)

 lselect(lst, starts_with("a") & !ends_with("c"))
