Calculation of macrozoobenthic ISS index (Basset et al. 2012, Barbone et al. 2012). Given as input a dataset with macrozoobenthic individual observations (individuals occurence and body size), produce as output a list of ISS values per site. Weight values for species richness have been setted according to Basset et al. 2012, they can be modified from the script (lines 24-33).
-y_size: Identify the field with individual body sizes; value: 1 text string, column's name of dataset with size information (e.g. "AFDW")
-y_space: Define spatial grain; value: 1 text string, column's name of dataset with spatial information (e.g. "Station", "Location", "Region")
-y_time: Define temporal grain; value: 1 text string, column's name of dataset with temporal information or (e.g. "Week", "Month", "Year", or ""(no information))
-y_taxonomic: Define taxonomic grain for the analysis; value: 1 text string, column's name of dataset with taxonomic information (e.g. "Species", "Order", "Family", "Phylum")
