Adjacency matrix from spacemap and spacemap models

Output from spacemap and space is transformed into an adjacency matrix encoding a network.

adjacency(net, aszero = 1e-06)

Arguments

net	Object output from spacemap and space
aszero	Positive numeric value (defaults to 1e-6) indicating at what point to consider extremely small parameter estimates of \(\Gamma\) and \(\rho\) as zero.

Value

A list containing

• yy A \(p \times p\) adjancency matrix indicates an edge\(y_q - y_l\) when yy[q,l] == 1 and 0 otherwise.

• xy A \(p \times q\) adjancency matrix indicates an edge\(x_p - y_q\) when xy[p,q] == 1 and 0 otherwise.
