I suggest the panel.dotplot.tb in the HH package.
It is a lattice panel function and therefore works
with standard trellis formulas including conditioning
variables and grouping variables.
library(HH)
example(panel.dotplot.tb)
Since you define what you want in terms of Minitab, I mention
that this is available in the Graphs menu with Rcmdr when you
install the RcmdrPlugin.HH package.
