vm_l_mesh.RdThis function helps to analyse the patch structure the calculate process is, each patch is squared before the sums of them are calculated and the sum is standardized by the total landscape area. it is a aggregation metric.
vm_l_mesh(landscape)the input landscape image
the returned calculated values are 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
