Add a representation and its parameters.

Usage

addRepresentation(NGLVieweR, type, param = list())

Arguments

NGLVieweR	A NGLVieweR object.
type	Type of representation. Most common options are "cartoon", "ball+stick", "line", "surface", "ribbon" and "label". For a full list of options, see the "structureRepresentation" method in the official NGL.js manual.
param	Options for the different types of representations. Most common options are name, opacity, colorScheme, sele, colorValue and visibility.
