Wrap Torsion Angle Data

Description

Adjust angular data so that the absolute difference of any of the observations from its mean is not greater than 180 degrees.

Usage

wrap.tor(data, wrapav=TRUE, avestruc=NULL)

Arguments

`data`	a numeric vector or matrix of torsion angle data as obtained from `torsion.xyz`.
`wrapav`	logical, if TRUE average structure is also ‘wrapped’
`avestruc`	a numeric vector corresponding to the average structure

Details

This is a basic utility function for coping with the periodicity of torsion angle data, by ‘wraping’ angular data such that the absolute difference of any of the observations from its column-wise mean is not greater than 180 degrees.

Value

A numeric vector or matrix of wrapped torsion angle data.
