Learn a DAG with undirected graph as starting point

I have an undirected graph (i.e. a set of undirected arcs). Bnlearn package doesn't seem to allow to learn from an undirected graph/network. For eg giving undirected graph for 'start' parameter in hill-climbing hc() function gives error "the graph…

Fit undirected Bayesian Network with bnlearn

I learnt Bayesian Network (BN) structures with the bnlearn package in R. However, for some of my BN, I have undirected edges. Thus, when I want to fit the BN (i.e. learn the Conditional Probability Tables = CPT), I obtain this error message telling…
