Prune each tree in forest using a given complexity parameter.

Prunes each tree in the list forest$Trees according to the provided complexity parameter. Returns a new forest.

pruneForest(forest, cp)

Arguments

forest	A model returned by splineForest()
cp	The complexity parameter that will be used to prune each tree (see rpart package documentation for detailed description of complexity parameter)

Value

A new splineforest object where each tree has been pruned to the desired level.

Examples

print(avSize(forest))
#> [1] 5.6
#> [1] 5.6
print(avSize(pruneForest(forest, cp=0.007)))
#> [1] 5.6
#> [1] 5.6
print(avSize(pruneForest(forest, cp=0.01)))
#> [1] 4.1
#> [1] 4.1
