dagR (version 1.1.1)

brute.search: Evaluate all possible adjustment sets of a DAG.

Description

Evaluates all adjustment sets of a DAG, optionally including adjustment sets including "unknown" nodes. If the DAG has a non-empty adjustment set, only adjustment sets including these adjustment variables are evaluated.

Usage

brute.search(dag, allow.unknown = FALSE, trace = TRUE, stop = 0)

Arguments

dag

The DAG to be evaluated.

allow.unknown

Boolean indicating "unknown" nodes should be featured in the adjustment sets to be evaluated (TRUE) or not (FALSE=default).

trace

Boolean indicating if some output should be produced (TRUE=default).

stop

If =0, all eligible adjustment sets are evaluated. If =1, evaluations are stopped after the first sufficient adjustment set has been evaluated. Defaults to 0.

Value

• A dataframe with the first columns (X1..Xn) indicating the variables in the respective adjustment set evaluated. The column totalPaths indicates the number of paths found when adjusting for the respective set, and openPaths indicates the number of biasing paths.

Examples

bs<-brute.search(demo.dag1(), trace=FALSE);
bs;
