Rejects a node/hypothesis and updates the graph accordingly.

Usage

rejectNode(graph, node, upscale = FALSE, verbose = FALSE, keepWeights = FALSE)

graph: A graph of class graphMCP or entangledMCP.
node: A character string specifying the node to reject.
upscale: Logical. If upscale=TRUE then the weights of all non-rejected nodes are scaled so that the sum is equal to 1. This forces keepWeights=FALSE to reduce confusion, since otherwise the sum of weights could become bigger than 1.
verbose: Logical scalar. If TRUE verbose output is generated during sequentially rejection steps.
keepWeights: Logical scalar. If FALSE the weight of a node without outgoing edges is set to 0 if it is removed. Otherwise it keeps its weight.

An updated graph of class graphMCP or entangledMCP.
