Description
Circular-Linear Copulas with Angular Symmetry for Movement Data.
Description
Classes (S4) of circular-linear, symmetric copulas with corresponding methods, extending the 'copula' package. These copulas are especially useful for modeling correlation in discrete-time movement data. Methods for density, (conditional) distribution, random number generation, bivariate dependence measures and fitting parameters using maximum likelihood and other approaches. The package also contains methods for visualizing movement data and copulas.

cylcop
The goal of cylcop is to provide methods to apply circular-linear copulas to capture correlation in discrete time movement data, i.e. step lengths and turn angles.
Installation
You can install the released version of cylcop from CRAN with:
install.packages("cylcop")
And the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("floo66/cylcop")
