Description
the food chains can allow circles/loop. This function will return all unique
food chains that involved the focused species as a node
, and the duplicated chains are deleted. It is recommended to use rather than
the function 'pathways'.
Usage
1
uniquepaths(gemat, sp)
Arguments
gemat
standard square graph matrix
sp
the species you want to search.
Value
return a list showing all food chains by presenting each node in that chain.
Also, the weights for each link will be returned as well.
