In causalDisco: Tools for Causal Discovery on Observational Data

Deparse a Knowledge Object into Knowledge DSL Code

Description

Given a Knowledge object, return a single string containing the R code (using knowledge(), tier(), ⁠%-->%⁠, and ⁠%!-->%⁠. that would rebuild that same object.

Usage

deparse_knowledge(kn, df_name = NULL)

Arguments

kn	A Knowledge object.
df_name	Optional name of the data frame you used (used as the first argument to knowledge()). If NULL, knowledge() is called with no data frame.

Value

A single string (with newlines) of R code.

Examples

# turn a Knowledge object back into DSL code
data(tpc_example)

kn <- knowledge(
  tpc_example,
  tier(
    child ~ starts_with("child"),
    youth ~ starts_with("youth"),
    old ~ starts_with("old")
  ),
  child_x1 %-->% youth_x3,
  oldage_x6 %!-->% child_x1
)

code <- deparse_knowledge(kn, df_name = "tpc_example")
cat(code)

# Explicitly add all forbidden edges implied by tiers
kn <- convert_tiers_to_forbidden(kn)
code <- deparse_knowledge(kn, df_name = "tpc_example")
cat(code)
