The tourr package for R produces tours of multivariate data, including grand, guided, and little tours, which project multivariate data (p-D) down to 1, 2, 3, or, more generally, d-D. The projected data can be rendered as densities or histograms, scatterplots, anaglyphs, glyphs, scatterplot matrices, parallel coordinate plots, time series or images, and viewed using an R graphics device, passed to ggobi, or saved to disk. A tour path can be stored for visualisation or replay. With this package it is possible to quickly experiment with different, and new, approaches to tours of data.
