The rpart and party packages, among others, calculate recursive
partitioning trees
for regression and classification. There are plot methods available for
showing
various features as, well, trees.
But trees can be displayed more compactly as treemaps, eg with the
treemap packge,
giving a recursive partitioning of a unit rectangle.
I'm wondering if anyone has tried to map the output from rpart() or
party::ctree() into
the form required as input for a treemap in R.
