releaf: "Re-leaf" a Vine

In vincenzocoia/copsupp: Vine Copulas made easy

Description

Convert a vine array (releafvarray) or a vine (releaf.rvine) so that a variable of your choice appears last in the vine array – if possible. This might only work for regular vines, with arrays truncated in the traditional sense.

Usage

releafvarray(G, leaf)

## S3 method for class 'rvine'
releaf(rv, leaf)

Arguments

G	Regular vine array.
leaf	Vector of variables that you want to get new vine array for, if such a vine array exists.
rv	Object of type "rvine".

Value

A vine array or vine with leaf at the end, if such a vine array exists; NULL otherwise.
