##### Geometric random graphs

Generate a random graph based on the distance of random point on a unit square

Keywords
graphs
##### Usage
sample_grg(nodes, radius, torus = FALSE, coords = FALSE)grg(...)
##### Arguments
nodes

The number of vertices in the graph.

The radius within which the vertices will be connected by an edge.

torus

Logical constant, whether to use a torus instead of a square.

coords

Logical scalar, whether to add the positions of the vertices as vertex attributes called ‘x’ and ‘y’.

...

Passed to sample_grg.

##### Details

First a number of points are dropped on a unit square, these points correspond to the vertices of the graph to create. Two points will be connected with an undirected edge if they are closer to each other in Euclidean norm than a given radius. If the torus argument is TRUE then a unit area torus is used instead of a square.

##### Value

A graph object. If coords is TRUE then with vertex attributes ‘x’ and ‘y’.
