as_bnlearn_knowledge: Convert Knowledge to bnlearn Knowledge

In causalDisco: Tools for Causal Discovery on Observational Data

Convert Knowledge to bnlearn Knowledge

Description

Converts a Knowledge object to a list of two data frames, namely whitelist and blacklist, which can be used as arguments for bnlearn algorithms. The whitelist contains all required edges, and the blacklist contains all forbidden edges. Tiers will be made into forbidden edges before running the conversion.

Usage

as_bnlearn_knowledge(kn)

Arguments

kn	A Knowledge object. Must have no tier information.

Value

A list with two elements, whitelist and blacklist, each a data frame containing the edges in a from, to format.

Examples

# produce whitelist/blacklist data frame for bnlearn
data(tpc_example)

kn <- knowledge(
  tpc_example,
  tier(
    child ~ starts_with("child"),
    youth ~ starts_with("youth"),
    oldage ~ starts_with("old")
  ),
  child_x1 %-->% youth_x3
)

bnlearn_kn <- as_bnlearn_knowledge(kn)
print(bnlearn_kn)
