This calculates Burt's network constraint for all egos in an egor object. It iterates over each network and applies igraph::constraint. A weight variable can be specified.

ego_constraint(object, weights = NULL, ego.alter.weights = weights)

Arguments

object

An egor object.

weights

Character, naming the alter-alter tie weight variable.

ego.alter.weights

Character, naming the ego-alter weight tie weight variable. This defaults to the same value as weights, only specify if the name of the ego.alter.weights is different from weights.

Value

Numeric vector with a constraint value for each ego.

Details

The calculation of weighted network constraint only works, if the alter-alter tie weights are complemented by a alter level variable specifying the same weight for the ego-alter ties.
