Radviz (version 0.9.3)

Project Multidimensional Data in 2D Space

Description

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 Ankerst *et al.* (1996) () for original implementation, see Di Caro *et al* (2012) () for the original method for dimensional anchor arrangements, see Demsar *et al.* (2007) () for the original Freeviz implementation.
