Usage

test.updated.bn(x)
"test.updated.bn"(x)

x

an InferenceEngine.

TRUE if an updated network is contained in the InferenceEngine, FALSE otherwise.

Examples

## Not run: 
# dataset <- BNDataset("file.header", "file.data")
# bn <- BN(dataset)
# ie <- InferenceEngine(bn)
# test.updated.bn(ie) # FALSE
# 
# observations(ie) <- list("observed.vars"=("A","G","X"), "observed.vals"=c(1,2,1))
# ie <- belief.propagation(ie)
# test.updated.bn(ie) # TRUE
