estimated_ancestral_va: Estimated Generalized Procrustes Analysis (GPA) coordinates of ventral anchors of root ancestor

Description

Estimated GPA landmark configuration of the ventral anchors of the root ancestor of 13 Ligophorus species.

Usage

data(estimated_ancestral_va)

Format

A matrix of 11 rows (landmarks) and 2 columns (xy-coordinates) representing the estimated GPA landmark configuration of the ventral anchors of the root ancestor (left and right anchors averaged).

Details

The root ancestor's GPA landmark configuration is unknown, but can be estimated using similar data from extant species. The estimation is done using fastAnc function in the phytools package (Revell, 2012). Root ancestor mean GPA coordinates of anchor landmarks are required for shape evolution analysis.
