Dist_mat_edge: Clustered edge population distribution.

In BenjamenSimon/EpidemicR: Stochastic modelling and inference for epidemics.

Description

This function generates a distance matrix for a population that is clustered on the left and right edges of the space only.

Usage

Dist_mat_edge(N, xlim = 20, ylim = 20, clusters = 8)

Arguments

N	The total number of individuals in the population.
xlim	The width of the plane on which individuals will be generated (defaults to 20 units wide).
ylim	The height of the place on which individuals will be generated (defaults to 20 units high).
clusters	The total number of clusters. Half the clusters will be on the right edge, the other half on the left. (Must be even, greater than 2, and divide N). Clusters are generated on blocks of size (xlim/10, ylim/10).

Value

The function returns a list. The first object in the list is a Nx2 matrix of the coordinates of the individuals. The second object is an NxN distance matrix.

Examples

xy.coords <- Dist_mat_edge(N=100, xlim = 20, ylim = 20, clusters = 10)[[1]]
distance_mat <- Dist_mat_edge(N=100, xlim = 20, ylim = 20, clusters = 10)[[2]]
plot(xy.coords[,1], xy.coords[,2], type  = "p")
