POI-class: Class "POI" as Points Of Interest

In fisheyeR: Fisheye and Hyperbolic-space-alike Interactive Visualization Tools in R

Description

A Class representing a set of elements and its relations. See references for details.

Objects from the Class

Objects can be created by calls of the form new("POI", ...). A POI object contains elements neccesary for representing relations.
