Parse a structural function (or exogenous probability)

Parses a string representing a structural equation or probability and converts it into an R function. Variable names appearing in the equation become arguments to the resulting function. Numeric inputs are interpreted as exogenous probabilities.

Usage

create_structural_function(equation_string)

Arguments

equation_string

A string representing a structural equation, or a numeric value representing an exogenous probability.

Value

An R function implementing the structural equation or, for an exogenous variable, a function returning its probability.

Details

For example, "a & b" is converted into a function equivalent to function(a, b) a & b.
