[R-sig-Geo] fattening certain portions of a city map in R with using projections

hi, i'm trying to map new york city and wondering if it's possible to pick
a projection that will have an effect that brings the map a bit closer to
the shapes seen in the nyc mta subway map  (

the bonne and azimuthal projections on this page (
https://en.wikipedia.org/wiki/List_of_map_projections) really appear to
inflate africa the same way that i would like to inflate either manhattan
or perhaps manhattan + brooklyn.


i've posted reproducible code and some example images here--

i understand what i'm trying to do could be accomplished as a cartogram,
but i'm curious if - since i don't really care about population- or
count-based weighting - a smart projection selection might save me a lot of
time.

thank you!!
