+\title{Annotation of features using \code{biomaRt}}

+\usage{

+  annotFeaturesWithBiomaRt(features, featureId, geneId,

+}

+\arguments{

+  \item{features}{Feature IDs to be annotated}

+

+  \item{featureId}{The type of the feature IDs, in the

+  \code{biomaRt} way (type \code{listFilters(mart)} to

+  choose one)}

+

+  \item{geneId}{The type of the gene IDs, in the

+  \code{biomaRt} way (type \code{listAttributes(mart)} to

+  choose one)}

+

+  \item{mart}{The mart object (database and dataset) used

+  for annotation, see function \code{useMart} of package

+  \code{biomaRt}}

+}

+\value{

+  A vector of gene IDs indexed by the feature IDs.

+}

+\description{

+  This function annotates a set of features using
