Perimeter-Area Fractal Dimension(vector data) — vm_l

This function allows you to get the result of 2 divided by ß, ß is the slope of the regression of the area against the perimeter in logarithm of all patches in a categorical landscape in vector data format

vm_l_pafrac(landscape)

Arguments

landscape: the input landscape image,

Value

the returned calculated slope is in column "value", and this function returns also some important information such as level and metric name, Moreover, class number and the "id" column, although both are "NA" here in the landscape level

Examples
