}
\arguments{
\item{n}{Number of vertices.}
\item{edges}{Number of edges per step.}
\item{agebins}{Number of aging bins.}
\item{pref}{Vector (\code{sample_last_cit()} and \code{sample_cit_types()} or
matrix (\code{sample_cit_cit_types()}) giving the (unnormalized) citation
probabilities for the different vertex types.}
\item{directed}{Logical scalar, whether to generate directed networks.}
\item{...}{Passed to the actual constructor.}
\item{types}{Vector of length \sQuote{\code{n}}, the types of the vertices.
Types are numbered from zero.}
\item{attr}{Logical scalar, whether to add the vertex types to the generated
graph as a vertex attribute called \sQuote{\code{type}}.}
}
\value{
A new graph.
}
\description{
\code{sample_last_cit()} creates a graph, where vertices age, and
gain new connections based on how long ago their last citation
happened.
}
\details{
\code{sample_cit_cit_types()} is a stochastic block model where the
graph is growing.
\code{sample_cit_types()} is similarly a growing stochastic block model,
but the probability of an edge depends on the (potentially) cited
vertex only.
