network.dyadcount {network} | R Documentation |
network.dyadcount
returns the number of dyads within a network
, removing those flagged as missing if desired. If the network is directed, directed dyads are counted accordingly.
network.dyadcount(x, na.omit = TRUE)
x |
an object of class |
na.omit |
logical; omit edges with |
The return value network.dyadcount
is equal to the number of dyads, minus the number of NULL
edges (and missing edges, if na.omit==TRUE
). If x
is directed, the number of directed dyads is returned.
The number of dyads in the network
