R help - Jul 2005 - stripchart usage and alternatives

r=1:10
u=c("a","a","a","b","b","b","c","d","e","e")
uf = factor(u)
rm = tapply(r, uf, mean)

stripchart(r~u,vertical=TRUE,pch=21)
stripchart(rm~levels(uf),vertical=TRUE,pch=3,add=TRUE)

----------
the above code creates a scatter plot of nominal data

are there alternatives to generate the same or similar
"kind" of figure? 


TIA,
Mike
