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:
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.
