That is probably the cleanest answer for now (I tried something like
that with as.vector(), but lost the names).  Another reasonable option
would be:
dotchart(unclass(table(infert$education)))

2D tables work fine presently:  dotchart(table(state.division, state.region))

I started a thread on R-devel suggesting a few possible solutions, so
perhaps in the next release, dotchart() will be able to handle table
class objects without any coercion.
