Residual-based Shadings in vcd

This vignette is a companion paper to Zeileis, Meyer, and Hornik (2005) which introduces several extensions to residual-based shadings for enhancing mosaic and association plots. The paper introduces (a) perceptually uniform Hue-Chroma-Luminance (HCL) palettes and (b) incorporates the result of an associated significance test into the shading. Here, we show how the examples can be easily reproduced using the vcd package.
