See the ‘dots’ function in the ‘TeachingDemos’ package or the ‘dotPlot’ (not 
to be confused with ‘dotplot’) function in the ‘BHH2’ package. Note that 
both packages define a ‘dots’ function, and one of them with mask the other 
if you load both packages.

You might also be interested in the ‘stem’ function (part of the default R 
packages).
