utility.endnode.firstavail.create {utility}

Construct an end node to get the results of the first available sub-node

Description

Function to construct a node that returns the results of the first sub-node for which results are available.

Usage

utility.endnode.firstavail.create(name.node, 
                                  nodes, 
                                  utility      = TRUE, 
                                  required     = FALSE, 
                                  col          = "black", 
                                  shift.levels = 0)

Arguments

name.node

name of the node to be constructed as a character string.

nodes

list of nodes to be tried.

utility

(optional) logical variable indicating if a value function (FALSE) or a utility function (TRUE) is created. Default value is TRUE.

required

(optional) logical variable indicating if the value of this node is required for aggregation at the next higher level. If this variable is TRUE, aggregation at the next higher level is not possible if this node returns NA. Default value is FALSE.

col

(optional) color used for plotting the bounding box of the node in the objective hierarchy. Default value is "black".

shift.levels

(optional) number of hierarchical levels by which the node in the objective hierarchy is shifted to make a branch fit better to other branches. Default value is 0.

Value

The function returns the created object of type utility.endnode.firstavail with the properties specified in the arguments of the function.
