[R] Plotting minimum spanning tree in graph/RBGL

I wonder if anyone could tell me how I can plot a Minimum Spanning Tree
using the functions provided in the "graph" and "RBGL" packages?
I am able to build the MST using the following set of commands:
> x <- read.table("h:/pole.tab",header=T,row.names=1)
> y <- dist(x)
> g1 <- new("distGraph",y)
> g2 <- mstree.kruskal(g1)
However, there doesn't seem to be a function that allows the command
"plot(g2)" to draw it.
