Returns the decision of the (optimal) Bayes classifier for a given data set. This is a generic function, i.e., there are different methods for the various mlbench problems.
If the classes of the problem do not overlap, then the Bayes
decision is identical to the true classification, which is
implemented as the dummy function
z$classes and is used for all problems with
- An object of class
# 6 overlapping classes p <- mlbench.2dnormals(500,6) plot(p) plot(p$x, col=as.numeric(bayesclass(p)))
