Hello Michael,
you have made a small mystake in your code:
use
gfrance -map.text('france', regions=depts, add=FALSE)
But I think that, it would be quite difficult to do what you need in R.
It is more a GIS problem.
I think that your problem can be better treated if you can create your map

Hello. I do not know if you can merge polygons, but you can select easily:
departements=map('france',namesonly=T) # returns a vector of names of
regions
map('france',regions=departements[1:20],namesonly=T) # use what you need
with regions argument
Hope this helps,

To do this, I have to adjust the modern map,
