Dear All, I would like to extract Lambda Sets from a binary matrix that represents a social network. The calculation of Lambda Sets is set out in Borgatti 1990 (which can be downloaded freely). The package SNA goes part of the way with the function MaxFlow but does not have the Lambda partitioning - but perhaps it is called differently in R. Does anyone know if it exists as a function or if there is a sequence functions to replicate it? Many thanks for any guidance on this. Best, Nick
