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.
