Treemaps are also closely related to mosaic displays. In package "vcd"
there is a very flexible implementation of mosaics provided by mosaic()
(based on the workhorse function strucplot()). We've been playing
around with providing a simple treemap implementation based on
strucplot(), but did not get around to put it into a user-friendly
interface. However, it is not so difficult to produce simple
treemaps with mosaic() by setting up a table with the splitting
variables and corresponding areas.
