randFRY: Random data for Fry analysis

Description

Random distribution of points that have a specified radial spacing.

Usage

randFRY(N = 200, LIM = c(0, 0, 100, 100), rlen = 5, PLOT=FALSE)

Arguments

N

integer, number of points

LIM

Limit in x-y direction

rlen

distance length. points are selected if they are greater than this distance from each other.

PLOT

logical, TRUE=make a plot of data

Value

x

x-coordinate

y

y-coordinate

Details

A spatial data set is generated that has random distribution with points no closer than a specified distance apart.
