Hi guys, Thanks a ton for your quick responses. Emma, the CV scores were so tempting to use for comparison to other variables...What would you suggest would be a more appropriate index to use in order to compare the shape ordination results to say, environmental variables, such as sediment size (I am studying clam morphology differences)?
