ego_constraint: Calculate Burt constraint for the egos of ego-centered networks
Description
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.
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.
