%description
Calculating silhouette information for clusters on circular or linear data
using fast algorithms. These algorithms run in linear time on sorted data,
in contrast to quadratic time by the definition of silhouette. When used
together with the fast and optimal circular clustering method FOCC
(Debnath & Song 2021) <doi:10.1109/TCBB.2021.3077573> implemented in R
package 'OptCirClust', circular silhouette can be maximized to find the
optimal number of circular clusters; it can also be used to estimate the
period of noisy periodical data.
