To get an overview how CART tesselates the space we can plot the tesselations
in two dimensional projections of the data. The quantlet
plotcart2
allows the user to interactively change the projections. Also
interactively we can choose if we want to see all cuts to a
specified level (see depth) or all cuts where the sum of
squared residuals (see ssr) is above a specified limit.
Note: if you view the cuts at the projection then be aware that
cuts could appear in the tree which ar not visible. Thus the plot
has to be interpreted with care! Additionally the plot can only
be applied to projections of continuous variables.
