Sebastian Sauer demonstrates using the pmap() function in purrr to call a function multiple times with different parameters:
Assume you have to call a function multiple times, but each with (possibly) different argument. Given enough repitioons, you will not want to repeat yourself.
In other words, we would like to loop over function arguments, each round in the loop giving the respective argument’value(s) to the function.
This is one of the benefits of functional-style programming: loops become higher-order functions, which take less time to write and keeps your code from looking like a pyramid of doom.
