In julianfaraway/facer: Analyze Facial Motion Data

This R package contains code supporting the analysis of facial shape and motion by Julian Faraway

You can install it (provided you have loaded the devtools package) with:

install_github("julianfaraway/facer")

The functions available are:

arraymean                           Array mean
