Two places that have worked examples leap to mind:
--- Sarkar's online accompaniment to his book:

Thumbing through the hard copy I see Figure 6.5 might of interest.
--- Addicted to R's graphics gallery:

I'm trying to create a fairly basic map using R. What i want to get
is the
map of the country with circles representing a count of students in
each
state.
What I've done so far is as following -
map("state")
symbols
(data1$count,circles=log(data1$count)*3,fg=col,bg=col,add=T,inches=F)
this gives me the map of the country, but one that's not populated
by my
counts.
Does anyone know what I'm doing wrong?
Also, if anyone can recommend a good reference for creating maps in
R, I'd
really appreciate that.
thank you
