I just installed and loaded ``uroot'' and tried your test example.
It worked without any complaint. This is under

Your problem must be specific to (a) your version of R (is it the

or (b) your operating system (both of which you should have specified
in your
post), or (c) to your local environment --- with which it would be
difficult
to provide any assistance.
