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")
