network.density: Compute the Density of a Network
In network: Classes for Relational Data

Description Usage Arguments Details Value Warning Author(s) References See Also Examples

network.density computes the density of its argument.

1	network.density(x, na.omit=TRUE, discount.bipartite=FALSE)

`x`	an object of class `network`
`na.omit`	logical; omit missing edges from extant edges when assessing density?
`discount.bipartite`	logical; if `x` is bipartite, should “forbidden” edges be excluded from the count of potential edges?

The density of a network is defined as the ratio of extant edges to potential edges. We do not currently consider edge values; missing edges are omitted from extent (but not potential) edge count when na.omit==TRUE.

The network density.

network.density relies on network attributes (see network.indicators) to determine the properties of the underlying network object. If these are set incorrectly (e.g., multiple edges in a non-multiplex network, network coded with directed edges but set to “undirected”, etc.), surprising results may ensue.
