Apply Summary Function Across Random Draws

Description

Summarise the distribution of random draws in an rvec, using a function.

Usage

draws_fun(x, fun, ...)

## S3 method for class 'rvec'
draws_fun(x, fun, ...)

Arguments

x	An object of class rvec.
fun	A function.
...	Additional arguments passed to fun.

Value

The results from calls to fun, combined using vctrs::vec_c().
