Dear all,
Attached there is a table, with columns "subparcel", "nrindividual", "diameter".
Within each subparcel, for each "nrindividual" I need to sum up the diameter of others "nrindividuals"  lying in the subparcel, which "diameter" is larger than or equal the fixed "nrindividual", excluding the diameter of the  fixed individual.
To summarize, I need to visit each individual inside the subparcel and find the others individuals in the same sub-parcel that have the diameter larger than or equal the visited individual and sum their diameter and return these information in a table, having "visited individual", "Subparcel", "diameter sum". I also need to perform these for n subparcels!
Thanks!
