plot.ace

Plot ace Objects

Description

This function plots objects of class "ace" or "pace" .

Usage

## S3 method for class 'ace'
plot(x, ...)

## S3 method for class 'pace'
plot(x, ...)

Arguments

`x`	An object of class `"ace"` or `"pace"`.
`...`	Arguments to be passed to and from other methods.

Value

A trace plot of the current evaluations of the approximate expected utility function. Separate lines are produced for the traces from Phases I and II of the ACE algorithm.

For objects of class "pace", the evaluations of the approximate expected utility function are from the repetition which resulted in the terminal design (see pace, paceglm, and pacenlm for more details).

These trace plots can be used to assess convergence. See Overstall & Woods (2017) for more details.

Note

For an example see ace.
