Register a pre-processing hook run before estimation begins

`fun` must take four arguments (`ui`, `est`, `data`, `control`) and return a list with any of `'ui'`, `'est'`, `'data'`, `'control'` to override; a non-returned element is left unchanged.

Usage

preProcessHooksAdd(name, fun)

Arguments

name

Character vector representing the name of the hook

fun

The function to run

Value

The function that was added (invisibly)
