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
