Description

A simple diagnostic plot showing the coverage of fossil taxa in modern calibration set

Usage

1
coverage.plot(mod,fos, rare=5, identify=FALSE)

Arguments

mod

Modern calibration set species data

fos

Fossil species data

rare

Value of Hill's N2 below which species are highlighted

identify

Whether to identify selected taxa.

Details

Finds the maximum abundance of fossil taxa and plots this against the maximum abundance the taxa in the modern calibration set. Taxa with a Hill's N2 less than rare in the calibration set are highlighted in blue. Taxa absent from the calibration set are highlighed in red. If there are many taxa above the 1:1 line, or important fossil taxa have a low N2 in the calibration set, reconstructions should be interpreted with caution.

Value

An invisible data.frame with the modern and fossil maximum abundances and N2 in the calibration set.
