)
}
\arguments{
\item{graph}{The input graph, it can be directed or undirected.}

\item{mapping}{A numeric vector that specifies the mapping. Its elements
correspond to the vertices, and for each element the id in the new graph is
given.}

\item{vertex.attr.comb}{Specifies how to combine the vertex attributes in
