## Package ‘circular’: summary information

It originally started as a porting from S-plus to R of functions developed for the book: Circular Statistics, from "Topics in circular Statistics" (2001) S. Rao Jammalamadaka and A. SenGupta, World Scientific. Now, it has an S3 implementation and several new functions and datasets.

### Version
