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. 
For those who do not have access to S-Plus, an alternative would be to download a FREE 
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 
library that can be downloaded also FREE, from the website 
http://cran.r-project.org/web/packages/CircStats/index.html
