Aloha. I have data that is in UTM4N (meters) and when I plot it using
p1 = ggplot(HI_L0_26904) +
geom_sf(aes(fill=NAME)) + coord_sf(crs = st_crs(26904))
It plots with geographic coordinates. Nothing I've read seems to work. I've checked the st_crs and it is correct. The geometry coordinates are in the correct units so it must have to do with ggplot somehow.
Mahalo.
