本文介绍了一个R软件包，它产生多变量数据的图尔斯。该软件包包括用于创建不同类型的图尔斯的函数，包括大的、引导的和小的图尔斯，其将多变量数据（p-D）向下投影到1、2、3或更一般地d（≤ p）维。投影数据可以呈现为密度或直方图，散点图，Anaglyphs，字形，散点图矩阵，平行坐标图，时间序列或图像，并使用R图形设备查看，传递到Gogobi或保存到磁盘。可以存储游览路径以进行可视化或回放。有了这个软件包，就可以快速试验不同的、新的数据图尔斯之旅方法。本文包含可以使用Adobe Acrobat PDF查看器查看的动画。
This paper describes an R package which produces tours of multivariate data. The package includes functions for creating different types of tours, including grand, guided, and little tours, which project multivariate data (p-D) down to 1, 2, 3, or, more generally, d (≤ p) dimensions. 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. This paper contains animations that can be viewed using the Adobe Acrobat PDF viewer.
