\title{Check d-separation criterion}
\usage{
\method{dsep}{lvm}(object, x, cond = NULL, return.graph = FALSE, ...)
}
\arguments{
\item{object}{lvm object}
\item{x}{Variables for which to check for conditional independence}
\item{cond}{Conditioning set}
\item{return.graph}{If TRUE the moralized ancestral graph with the
conditioning set removed is returned}
\item{...}{Additional arguments to lower level functions}
}
\description{
Check for conditional independence (d-separation)
}
\details{
The argument 'x' can be given as a formula, e.g. x~y|z+v
or ~x+y|z+v With everything on the rhs of the bar defining the
variables on which to condition on.
