Look at the subplot function in the TeachingDemos package.

Subject: [R] barplot and map overlay
Hi,
I wonder if it is possible with the graphics package to overlay one or several
plots
(barplots, for example) over a map. Data for the map is in a data frame with the
latitude and longitude coordinates, and then:
> plot(map$long, map$lat, type ="l")
produces the map. I want to put each barplot in specific locations on the map,
namely
at the center of "statistical squares".
I´ve seen an example in Paul Murrell´s "R Graphics" book that seems appropriate
(grid package), but a bit complicated.
Thanks a lot for any advice.
Héctor
