Correspondence Analysis in R, with Two- and Three-dimensional Graphics: The ca Package

摘要: We describe an implementation of simple, multiple and joint correspondence analysis in R. The resulting package comprises two parts, one for simple analysis. Within each part, functions computation, summaries visualization three dimensions are provided, including options to display supplementary points perform subset analyses. Special emphasis has been put on the that offer features such as different scaling biplots three-dimensional maps using rgl package. Graphical include shading sizing plot symbols according their contributions map masses respectively.
