Calculate the effective number of species in the fossil data

Source: R/Hill.N2.core.R
Hill.N2.core.Rd

Gives a measure of the species diversity in the fossil data.

Usage

Hill.N2.core(spp)

Arguments

spp

data.frame of Species data

Value

Minimum, first quartile and median effective number of species

Details

Uses rioja::Hill.N2() from the rioja package.

Note

If the effective number of species is small, WA based reconstructions are unlikely to be significant, and MAT based reconstructions should be tested instead.
