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
outside
Here's what I tried. I can plot a selection of regions, but I
can't seem to remove an arbitrary list of region numbers, unless I've
done something wrong
by selecting the regions I want to plot with departements[-exclude].
I also get an error
when I try to use map.text to label a map with only th

Hello. I do not know if you can merge polygons, but you can select easily:

regions

with regions argument
Hope this helps,

I'm doing some analyses of historical data from France in 1830 on 'moral
statistics' that I'd like to
show on a map. I've done most of my analyses in SAS, but a few things
would work better in R.
To do this, I have to adjust the modern map,
library(maps)
map('france')
to adjust for changes in d
