draw: Validation and diagnostic plots for a sequential design

Description

This function draws diagnostic and validation plots for a sequential design of a (D)GP emulator or a bundle of (D)GP emulators.

Usage

draw(object, ...)
# S3 method for gp
draw(object, type = "rmse", log = FALSE, ...)
# S3 method for dgp
draw(object, type = "rmse", log = FALSE, ...)
# S3 method for bundle
draw(object, type = "rmse", log = FALSE, emulator = NULL, ...)

Value

A patchwork object.

Arguments

object

can be one of the following emulator classes:

• the S3 class gp.

• the S3 class dgp.

• the S3 class bundle.

...

N/A.

type

specifies the type of plot or visualization to generate:

• "rmse": generates a trace plot of RMSEs, log-losses for DGP emulators with categorical likelihoods, or custom evaluation metrics specified via the "eval" argument in the [design()] function.

• "design": shows visualizations of input designs created by the sequential design procedure.

Defaults to "rmse".

log

a bool indicating whether to plot RMSEs, log-losses (for DGP emulators with categorical likelihoods), or custom evaluation metrics on a log scale when type = "rmse". Defaults to FALSE.

emulator

an index or vector of indices of emulators packed in object. This argument is only used if object is an instance of the bundle class. When set to NULL, all emulators in the bundle are drawn. Defaults to NULL.
