get_enn_patch: get_enn_patch

In r-spatialecology/landscapemetrics: Landscape Metrics for Categorical Map Patterns

get_enn_patch

Description

Euclidean Nearest-Neighbor Distance

Usage

get_enn_patch(classes, class_patches, points, resolution, verbose = FALSE)

Arguments

classes	A vector with unique values (output of get_unique_values_int)
class_patches	A list with matrices of patches for each class (output of get_class_patches)
points	A matrix with three columns: col, row, value (output of get_points)
resolution	A vector with two numbers (usually calculated using terra::res)
verbose	A logical indicating whether to print warnings

Details

Calculate Euclidean Nearest-Neighbor Distance for each patch in each class

Value

tibble with two columns: class, value

Examples

landscape <- terra::rast(landscapemetrics::landscape)
landscape_mat <- terra::as.matrix(landscape, wide = TRUE)
classes <- landscapemetrics:::get_unique_values_int(landscape_mat)
class_patches <- get_class_patches(landscape_mat, classes, directions = 8)
points <- get_points(landscape_mat, terra::res(landscape))
enns <- get_enn_patch(classes, class_patches, points, terra::res(landscape))
