treelet (1.0)
Treelets - an adaptive multi-scale basis for high-dimensional, sparse and unordered data.
http://cran.r-project.org/web/packages/treelet
Treelets provides a novel construction of multi-scale bases that extends wavelets to non-smooth signals. It returns a multi-scale orthonormal basis, where the final computed basis functions are supported on nested clusters in a hierarchical tree. Both the tree and the basis, which are constructed simultaneously, reflect the internal structure of the data.
