Hi Magnus, I stumbled upon your ITP when I wanted to inject this myself. I added you to the pkg-r-team - please be so kind to remove your private repository on Salsa to avoid confusion. In any case I've added you as Uploader. I'd recommend you subscribe to the team list[1] and bounce your ITPs there. I also intend to package r-cran-ggmap (as predependency for r-cran-choroplethr) but I'd like to wait whether ftpmaster might have issues with Google services before I keep on with this.
Kind regards Andreas. [1] https://lists.debian.org/debian-r/ -- http://fam-tille.de
