Here is an example using the subplot function.
library(TeachingDemos)
map("state", region= "ohio", xlim=c(-85, -80), ylim=c(38, 42))
tmp <- subplot(map("state",add=TRUE), 'bottomright', type='fig',
size=c(0.2,0.2), inset=0.1)
op <- par(fig=tmp$fig)
map("state", region="ohio", fill=T, add=T)
par(op)
With maps trying to redo the graphics parameters you need to play
around with the settings a little. subplot works better with
type='fig' with maps.
