[R] Function for extracting Lambda Sets

[Nick Duncan]

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
