Male and female macaque skull data. 7 landmarks in 3 dimensions, 18 individuals (9 males, 9 females)

Format

  • macaques$x: An array of dimension \(7 \times 3 \times 18\)

    macaques$group: A factor indicating the sex ('m' for male and 'f' for female)

Details

In an investigation into sex differences in the crania of a species of Macaca fascicularis (a type of monkey), random samples of 9 male and 9 female skulls were obtained by Paul O’Higgins (Hull-York Medical School) (Dryden and Mardia 1993). A subset of seven anatomical landmarks was located on each cranium and the three-dimensional (3D) coordinates of each point were recorded.
