Nothing
Crossvalidated linear discriminant calculations determine the optimum number of features. Test and training scores from successive crossvalidation steps determine, via a principal components calculation, a lowdimensional global space onto which test scores are projected, in order to plot them. Further functions are included that are intended for didactic use. The package implements, and extends, methods described in J.H. Maindonald and C.J. Burden (2005) <https://journal.austms.org.au/V46/CTAC2004/Main/home.html>.
