Convert to an index vector

vec_as_index() has been renamed to vec_as_location() and is deprecated as of vctrs 0.2.2.

vec_as_index(i, n, names = NULL)

`i`	An integer, character or logical vector specifying the locations or names of the observations to get/set. Specify `TRUE` to index all elements (as in `x[]`), or `NULL`, `FALSE` or `integer()` to index none (as in `x[NULL]`).
`n`	A single integer representing the total size of the object that `i` is meant to index into.
`names`	If `i` is a character vector, `names` should be a character vector that `i` will be matched against to construct the index. Otherwise, not used. The default value of `NULL` will result in an error if `i` is a character vector.
