DB_weightedIdx

Computation of weighted version of the Davies-Bouldin index. This index serves as a measure of clustering quality of a 2D projection result with known class labels

An implementation of the radviz projection in R. It enables the visualization of
multidimensional data while maintaining the relation to the original dimensions.
This package provides functions to create and plot radviz projections, and a number of summary
plots that enable comparison and analysis. For reference see Hoffman *et al.* (1999)
(<doi:10.1145/331770.331775>) for original implementation,
see Di Caro *et al* (2012) (<doi:10.1007/978-3-642-13672-6_13>),
for the original method for dimensional anchor arrangements, see Demsar *et al.* (2007)
(<doi:10.1016/j.jbi.2007.03.010>) for the original Freeviz implementation.
