\title{Filter GO terms by a specified GO ontology}
\description{
Given a character vector containing GO identifiers, return a logical
vector indicating which GO IDs are in the specified ontology (BP,
CC, or MF).
}
\usage{
filterGOByOntology(goids, ontology = c("BP", "CC", "MF"))
}
\arguments{
\item{goids}{a character vector of GO IDs}
\item{ontology}{One of "BP", "CC", or "MF"}
}
\value{
A logical vector with length equal to \code{goids}. A \code{TRUE}
indicates that the corresponding GO ID in \code{goids} is a member
of the ontology specified by \code{ontology}.
