This function allows you to calculate the perimeter of each patch in a categorical landscape in vector data format

vm_p_perim(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.
