k_tree: The 'k' trees closest to a sample location are selected into...

In AWF-GAUG/fisim: Forest Inventory Simulator (fisim) is a package for simulating response and samplign designs common in forest inventories.

Description

The k trees closest to a sample location are selected into the sample

Usage

k_tree(tree_pop, sample_loc, k = 6)

Arguments

tree_pop	A tree population object (tree_pop)
sample_loc	A sample location object (sample_loc) as provided by the xy_sample function.
k	Number of nearets neighbors.

Details

The RANN package is used to find the k trees clostest to the respective sample locations in sample_loc. The RANN package is a wrapper for the Approximate Near Neighbor (ANN) C++ library allowing for fast nearest-neighbor searches using kd-trees.

Value

An object of class response with indices of trees in tree_pop that are selected at the individual sample locations.
