randFRY: Random data for Fry analysis

In geophys: Geophysics, Continuum Mechanics, Gravity Modeling

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

Details

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

Value

x	x-coordinate
y	y-coordinate
