\title{A function to map probe identifiers to pathways. }
\description{
Given a set of probe identifiers from a microarray this function looks
up all KEGG pathways that the probe is documented to be involved in.
}
\usage{
probes2Path(pids, data = "hgu133plus2")
}

\arguments{
\item{pids}{A vector of probe identifiers. }
\item{data}{The character name of the chip. }
}
\details{
This is a simple look up in the appropriate chip \code{PATH} data
environment.
}
\value{
A list of pathway vectors. One element for each value of \code{pid}
that is mapped to at least one pathway.
