Method new()

Create a new ParallelWorld object from an SCM object.

Usage

ParallelWorld$new(scm, dolist, worldnames = NULL, worldsuffix = "_")

Arguments

scm

An SCM object.

dolist

A list containing the interventions for each world. Each element of the list has the fields:

• target: a vector of variable names that specify the target variable(s) of the counterfactual intervention.

• ifunction: a list of functions for the counterfactual intervention.

worldnames

A character vector giving the names of the parallel worlds.

worldsuffix

A text giving the suffix used for parallel world variables before the world number. Defaults to "_" and the worlds have then suffixes "_1", "_2", "_3", ...

Returns

A new `ParallelWorld` object that also belongs to class `SCM`.

Examples

backdoor_parallel <- ParallelWorld$new(
                        backdoor,
                        dolist=list(
                            list(target = "x", 
                                 ifunction = 0),
                            list(target = list("z","x"), 
                                 ifunction = list(1,0))
                        )
)
backdoor_parallel 
plot(backdoor_parallel)

Method clone()

The objects of this class are cloneable with this method.

Usage

ParallelWorld$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
