cyl_rot_combine {cylcop}

Construction of 'cyl_rot_combine' Objects

Description

Constructs a circular-linear copula of class 'cyl_rot_combine' from linear combinations of copulas.

Usage

cyl_rot_combine(copula, shift = FALSE)

Arguments

copula

linear-linear 2-dimensional 'Copula' object of the package 'copula'.

shift

logical value indicating whether the (u-periodic) copula should be shifted by 0.5 in u direction.

Value

An R object of class 'cyl_rot_combine'.
