qreach

Column of node in adjacency matrix, of which possible d-sep is
  to be computed

Adjacency matrix as returned by
  amat[i,j] = 0 iff no edge btw i,j
  amat[i,j] = 1 iff i *-o j
  amat[i,j] = 2 iff i *-> j

This function computes the Possible-D-Sep of node x in a partially
  directed acyclic graph (PDAG). It is intended
  for internal use only.

Standard and robust estimation of the equivalence class of
        a Directed Acyclic Graph (DAG) via the PC-Algorithm. The
        equivalence class is represented by its (unique) Completete
        Partially Directed Acyclic Graph (CPDAG). Furthermore, a PAG
        instead of a CPDAG can be estimated if latent variables and/or
        selection variables are assumed to be present. FCI and RFCI are
        available for estimating PAGs. Functions for causal inference
        using the IDA algorithm (based on do-calculus of Judea Pearl)
        are provided for CPDAGs.
