Euclidean Nearest-Neighbor Distance(vector data)

This function allows you to calculate the distance to the nearest neighbouring patch of the same class in meters The distance is measured from edge-to-edge.

Usage

vm_p_enn(landscape, class_col = NULL, patch_col = NULL)

Arguments

landscape: the input landscape image,
class_col: the name of the class column of the input landscape
patch_col: the name of the id column of the input landscape

Value

the function returns tibble with the calculated values in column "value", this function returns also some important information such as level, class, patch id and metric name.

Examples

vm_p_enn(vector_patches, "class", "patch")
