plotNetwork: Plot a circular map of network links between entities

Description

Plots a circular map of entities and their relationships. The entities are around the edge of the circle with lines linking the entities depending on their relationships as represented in the supplied FLOW argument. Line widths represent relative magnitude of flows, as do line colours, and the font size of a label for an entity represents the size of the total flow into that entity. Useful for displaying, for example, cash flows between entities.

Usage

plotNetwork(flow)

Arguments

flow

a square matrix of directional flows.

Details

The FLOW is a square matrix that records the directional flow and magnitude of the flow from one entity to another. The flow may represent a flow of cash from one company to another company. The dimensions of the square matrix are the number of entities represented.

Examples

# Create a small sample matrix.
flow <- matrix(c(0, 10000, 0, 0, 20000,
                 1000, 0, 10000, 0, 0,
                 5000, 0, 0, 0, 3000,
                 0, 1000000, 600000, 0, 0,
                 0, 50000, 0, 500000, 0),
               nrow=5, byrow=TRUE)
rownames(flow) <- colnames(flow) <- c("A", "B", "C", "D", "E")
plotNetwork(flow)

# Use data from the network package.
