Description

Find the direction away from the closest point

Usage

thigmophobe(x,y=NULL,names=seq_along(z),xlog=par("xlog"),ylog=par("ylog"),
  usr=par("usr"),pin=par("pin"),eps=.Machine$double.eps,pi=base::pi)

Value

A vector of directions away from the point nearest to each point.

Arguments

x,y
