isNodeUpstream(x, current_node, candidate_node)

Arguments

x

[GRiwrmInputsModel object] (see CreateInputsModel.GRiwrm) or [GRiwrm object] (See CreateGRiwrm)

current_node

character with the id of the current node

candidate_node

character with the id of the node for which we want to know if it is downstream or upstream current_node

Value

logical TRUE if the node with the id down_candidate is downstream or upstream the node with the id current_node
