get.expression: Get the expression of a probability object

In causaleffect: Deriving Expressions of Joint Interventional Distributions and Transport Formulas in Causal Models

Get the expression of a probability object

Description

This function converts an object of class probability returned by aux.effect, causal.effect, generalize, meta.transport, recover or transport with expr = FALSE into a string which represents the probability distribution. Currently only LaTeX syntax is available.

Usage

get.expression(x, primes = FALSE)

Arguments

x	An object of class probability which is an internal list structure describing the interventional distribution.
primes	A logical value. If TRUE, prime symbols are appended to summation variables to make them distinct from their other instantiations.

Value

A character string that describes the resulting distribution in LaTeX syntax.

Examples

library(igraph)

# simplify = FALSE to allow multiple edges
g <- graph.formula(X -+ Y, Z -+ X, Z -+ Y , X -+ Z, Z -+ X, simplify = FALSE) 

# Here the bidirected edge between X and Z is set to be unobserved in graph g
# This is denoted by giving them a description attribute with the value "U"
# The edges in question are the fourth and the fifth edge
g <- set.edge.attribute(graph = g, name = "description", index = c(4,5), value = "U") 

x <- causal.effect(y = "Y", x = "X", z = NULL, G = g, expr = FALSE)
get.expression(x, primes = FALSE)
get.expression(x, primes = TRUE)
