dsep

Test d-separation

Check whether two nodes are d-separated.

dsep(bn, x, y, z)

`bn`	an object of class `bn`.
`x,y`	a character string, the label of a node.
`z`	an optional vector of character strings, the label of the (candidate) d-separating nodes. It defaults to the empty set.

dsep() returns TRUE if x and y are d-separated by z, and FALSE otherwise.
