plotBarrierTree3D: Plot Barrier Tree in 3D

Description

Creates a 3D surface plot containing the barrier tree of this cell mapping.

Usage

plotBarrierTree3D(feat.object, control)

Arguments

feat.object

[FeatureObject] A feature object as created by createFeatureObject.

control

[list] A list, which stores additional control arguments. For further information, see details.

Value

• [plot]. A 3D-surface plot, visualizing the barrier tree of this cell mapping.

Details

Possible control arguments are:

• Computation of Cell Mapping

:

• gcm.approach

: Which approach should be used when computing the representatives of a cell. The default is "min", i.e. the observation with the best (minimum) value within per cell. gcm.cf_power: Theoretically, we need to compute the canonical form to the power of infinity. However, we use this value as approximation of infinity. The default is 256.

Examples

# create a feature object
X = createInitialDesign(n.obs = 900, dim = 2)
f = smoof::makeAckleyFunction(dimensions = 2)
y = apply(X, 1, f)
feat.object = createFeatureObject(X = X, y = y, fun = f, blocks = c(4, 6))

# plot the corresponing barrier tree
plotBarrierTree3D(feat.object)
