progressively: Progressively

In nflreadr: Download 'nflverse' Data

Progressively

Description

This function helps add progress-reporting to any function - given function f() and progressor p(), it will return a new function that calls f() and then (on exiting) will call p() after every iteration. This is inspired by purrr's safely, quietly, and possibly function decorators.

Usage

progressively(f, p = NULL)

Arguments

f	a function to add progressor functionality to.
p	a function such as one created by progressr::progressor() - also accepts purrr-style lambda functions.

Value

a function that does the same as f but it calls p() after iteration.
