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)

Arguments

x,y

Numeric data vectors. Typically the x/y coordinates of plotted points. If arrays are passed, they will be silently coerced to numeric vectors.

names

Names for the vector of directions.

xlog,ylog

Flags for logarithmic axes. See Note.

usr

pi

value of pi.
