lower.site.limit

The minimal number of sites a genralist can occur in. Must be a proportion, defaults to 0.5

Value

A matrix object with columns "No Sites", :Mean Abiundance" The mean abudance of that species across all sites it occurs, "Log abundance", the log of the total abundance of that species across all sites it occurs, and finally Specialist, generalist and nominal deliniation.
