Hi:

Are you looking for something like Figure 4.2 in the Lattice book?
http://lmdvr.r-forge.r-project.org/figures/figures.html
(Click on Figure 4.2)

If so, then try this:

dat<-data.frame(id=c("a","b","c"),val=c(-1,0,0.3))
dotplot(id~val,data=dat, origin = -1, type = c('p', 'h'))

The origin provides the starting point of val.

HTH,
Dennis
