Landmark data from heads and tails of larval Salamanders exposed to different treatments of herbicides.
Data set includes tail landmarks (coords), index for identifying semilandmarks (sliders), and vectors for variables including herbicide treatment (Treatment) and Family (Family). The latter variable indicates the egg masses (clutches) sampled in the wild from which individual eggs were randomly assigned to treatment. See Levis et al. (2016) for more experimental details.
