skulls.df {s20x} | R Documentation |
Male Egyptian skulls from five different epochs. Each skull has had four measurements taken of it, BH, Basibregmatic Height, BL, Basialveolar Length, MB, Maximum Breadth and NH, Nasal Height. It is of interest to investigate the change in shape over time. A gradual change, would indicate inbreeding of the populuations.
