Map state/providence divitions

[AgustinPardo]

Hello,

I am using the "pyhlo.to.map" function of the phytools library. Do you know How I could modify the Argentinian map to get the internal providence/state divisions?

I am running phylo.to.map function with the options:
database="worldHires" regions=c("Argentina")

and I get the Argentinian map like this:

I want something like this:

Do you know If I have to change the "database" or "regions" parameters of the function pthylo.to.map?

Also, I found this web with other formats of maps:
https://gadm.org/download_country_v3.htm
Do you know If I could include those maps with the phytools library?

Another option could be to change the internal map formats of the pythools library, but I don't know where they are and what formats they have. Could you show me?

Regards

Agustin
