[R] minimum spanning tree

[amir]

Hi,

I have a graph G with n nodes (n=1..100).

I want to find the spanning tree over only some specific nodes (not all
nodes in G), for instance nodes (2,3,6).
Is there any way in R that can do this?

Maybe one solution is create another subgraph g' of graph G which
consists nodes 2,3,6 and their edges.
Then running minimum.spanning.tree(g').

I want to know is there any better solution?

Regards,
Amir
