Force field simulation for a set of points

Description

Force field simulation of interaction of set of points. Very useful for placing text labels on graphs, such as scatterplots.

Details

FFieldPtRep(): Performs force field simulation of mutual repulsion by set of points.

FFieldPtRepDemo(): Demonstrates the utility of FFieldPtRep for placing labels in a scatterplot.

# Repel points

                             mtcars$mpg * 100 / max(mtcars$mpg)),
              rep.fact = 40)
head(mtcars)
