An Animation Device Driver for (new) S

The area of statistical graphics has progressed well beyond static displays with dynamic graphics playing an increasing role in teaching and data analysis. Much work in this area has been done on specialized workstations using specialized software. The systems are quite impressive. It is usually easy to use such systems given the requisite environment and an application that fits the designers vision. Otherwise, doing something a bit different requires detailed knowledge of the particular hardware and software. Our approach is to provide a crude but fast mechanism to animate statistical graphs in a common and widespread computing environment (UNIX).
