get.expression {causaleffect} | R Documentation |

## 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 |

`primes` |
A logical value. If |

### 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)
```
