Complexity Parameter Behaviour

We don't see much of the true behaviour of the complexity parameter with our small dataset. We can build a more interesting model based on the larger weatherAUS dataset from rattle.

If we build a default model then we can plot the complexity parameter as before.

tmodel <- rpart(form, ds[vars])
plotcp(tmodel)
