Package: mulgar 1.0.4

mulgar: Functions for Pre-Processing Data for Multivariate Data Visualisation using Tours

This is a companion to the book Cook, D. and Laa, U. (2023) <https://dicook.github.io/mulgar_book/> "Interactively exploring high-dimensional data and models in R". by Cook and Laa. It contains useful functions for processing data in preparation for visualising with a tour. There are also several sample data sets.
