loop (version 1.1)

lclw: find the largest weight food chain among the candidate longest food chains for a given node (species)

Description

Sometimes for a given species, it has many food chains that are equal in chain lengths and all are longest. This function thus will find out the one with largest weight.

Usage

lclw(gemat, sp)

Arguments

gemat

standard square graph matrix

sp

the node/species you want to search

Value

return the pathways and corresponding weights in a list
