fakeRivers: Generate fake river networks.

In fakeplace: Generate fake geographies

Description

Produce some wiggly lines that form a tree structure.

Usage

fakeRivers(n = 30, pts = cbind(runif(n), runif(n)))

Arguments

n	If this is the only argument, start with n points in a unit square.
pts	The points to use for initial seeds.

Details

Use the initial points to create Voronoi tiles. Wiggle the edges. Then use the distance between nodes as edge weight to create a minimum spanning tree. Return the edges of the tree.

Value

A list of 2-column matrix line segments.
