\title{Compute minimum spanning tree for an undirected graph}

\description{Compute minimum spanning tree for an undirected graph}

\usage{
mstree.prim(g)
prim.minST(g)
}

\arguments{
  \item{g}{an instance of the \code{graph} class with \code{edgemode}
    \dQuote{undirected}}
}

\details{
This is Prim's algorithm for solving the minimum spanning tree problem for an 
undirected graph with weighted edges. 

The function \code{prim.minST} is depricated and renamed, use 
\code{mstree.prim} instead.

See documentations on this function in Boost Graph Library for more details.
}

\value{
  A list of
\item{edges}{the edges that form the minimum spanning tree}
\item{weights}{the total weight of the minimum spanning tree}
}
