As simple wrapper around `vec_unique_count()`, that can easily take multiple vectors. Note that `tibble()` is slow so need to think about this, and probably use a lower-level constructor from vctrs....
| Vector | Summary | Cumulative | Parallel | Matrix | | --- | --- | --- | --- | --- | | `+` | `sum` | `cumsum` | |...
Since complicated `if_else()` statement can often be written much more simply. Should include something in description, and example of converting nested `if_else()` into `case_when()`.
Start from @DavisVaughan ```R lag
Something like this: ```R group_map
Provide some way to use `vec_compare()`, `vec_arith()`, etc within a session. Would use vctrs recycling and coercion rules.
``` r tibble::as_tibble(as.list(quantile(1:5))) #> # A tibble: 1 x 5 #> `0%` `25%` `50%` `75%` `100%` #> #> 1 1 2 3 4 5 ``` Created on 2019-02-08 by the...
Do we expect functions to have a common prefix? My sense is no: this is sort of a dplyr equivalent for functions.
