That did the trick! Thank you much, Richard Heiberger.

R works on the idea that factor level ordering is a property of the
data rather than a property of the graph. So if you have the factor
levels ordered properly in the data, then the graph will take care of
itself. To order the levels see functions like: factor, relevel, and
reorder.

of a cluster.
(2) run under R
