# Index of Circstats Programs

```The CircStats library contains the following functions, all of which have online help
available. Detailed descriptions of these programs as well as the programs  are available
from the book  "Topics in Circular Statistics" (2001). These programs have been written
using S-Plus, which is widely used in the universities and other academic settings.
version of a different language called R, to be found at http://cran.r-project.org/
by going to the "R Binaries" link under "Software". Then use an R version of the CircStats
