extracat.RdThis package offers a variety of functions that can be used for categorical data analysis or at least have to do with categorical data.
Among the most interesting features are
| rmb | |
| RMB plots visualize contingency tables. | |
| The function offers different visualizations of conditional distributions and their corresponding weights (frequencies) | |
| including multiple barcharts, spineplots and piecharts. There are different ways of displaying the residuals from statistical models. | |
| scpcp | |
| A static version of CPCP plots with labeling and color options. | |
| optile | |
| The OPTILE interface was developed for the Google Summer of Code 2011. | |
| It offers a variety of reordering techniques for contingency tables. | |
| The reordering of the categories not only improves visualizations. | |
| rmbmat | |
| A matrix of RMB plots not unlike a Scatterplot matrix (SPLOM) is produced. | |
| It uses binning for continuous data. | |
| hexpie | |
| After a hexagonal binning of x and y a third categorical target variable | |
| is displayed via piecharts (or embedded hexagons) within the hexagons. | This avoids problems with overplotting. |
| quickfechner | |
| A very fast implementation of the fechnerian scaling technique, | |
| which computes a fechnerian distance matrix from a (dis.)similarity matrix. | |
| The technique is equivalent to a shortest path algorithm. | |
| fluctile | |
| Offers two- or multidimensional fluctuation diagrams and multiple barcharts. | |
| arsim | |
| Simulates categorical data arrays of any dimension. | |
| The number of observations, the number of block clusters and the noise level and type can be chosen. | |
