Prune a Recursively Partitioned Point Process Model

Given a model which has been fitted to point pattern data by recursive partitioning, apply pruning to reduce the complexity of the partition tree.

Keywords
models, spatial
Usage
# S3 method for rppm
prune(tree, …)
Arguments
tree

Fitted point process model of class "rppm" produced by the function rppm.

Arguments passed to prune.rpart to control the pruning procedure.

Details

This is a method for the generic function prune for the class "rppm". An object of this class is a point process model, fitted to point pattern data by recursive partitioning, by the function rppm.

The recursive partition tree will be pruned using prune.rpart. The result is another object of class "rppm".

Value

Object of class "rppm".
