Not directly. You do need to change the plotting character (pch). Here
are two ways to do it (the second is longer but recommended):
dotplot(variety ~ yield | site, data = barley, groups = year, pch = c(1, 16))
dotplot(variety ~ yield | site, data = barley, groups = year,
auto.key = TRUE,
par.settings = list(superpose.symbol = list(pch = c(1, 16))))
