shortest.chain: find out the food chain with shortest length among all food...

In loop: loop decomposition of weighted directed graphs for life cycle analysis, providing flexbile network plotting methods, and analyzing food chain properties in ecology

Description

not including self-loop (i.e., the node itself as a chain)

Usage

shortest.chain(gemat, sp)

Arguments

gemat	standard square graph matrix
sp	the node/species you want to search
