trunCopula: Constructor of the truncated copula class.
In spcopula: Copula Driven Analysis - Multivariate, Spatial, Spatio-Temporal

Description Usage Arguments Value Author(s) Examples

Returns a class trunCopula representing a truncated copula where mass of a continuous copula is concentrated in the boubndary curve.

1	trunCopula(copula, contPar, approx.u = 1:1000/1000)

`copula`	the underlying continuous copula
`contPar`	The power 'p' of the polynomial boundary 'x^p'.
`approx.u`	a discretisation of the u-axis for numerical approximations
