CRS Out of Date

[neellab-umd]

Hi There -

I am getting the following error when I try to use urbnmapr maps as sf objects.
"old-style crs object detected; please recreate object with a recent sf::st_crs()"

The code I used is
counties_sf <- get_urbn_map("counties", sf = TRUE)

counties_sf %>%
ggplot(aes()) +
geom_sf(fill = "grey", color = "#ffffff")

Is there an easy workaround or are there plans to update the map CRSs?

I was trying to bring the map is as an sf object so I could plot a scale bar and north arrow. I don't seem to be able to add those things using ggspatial which works with sf objects. See errors with code below:

counties %>%
filter(state_name =="Florida") %>%
ggplot() +
geom_polygon( aes(long, lat, group = group),
color="black", fill = "gray80",size = 0.2) +
coord_map(projection = "albers", lat0 = 39, lat1 = 45)+
theme_map()+
theme(legend.position = c(0.1,0.6))+
ggspatial::annotation_scale(
location = "bl",
width_hint = 0.3,
height = unit(0.11, "cm"),
pad_x = unit(0.32, "in"),
pad_y = unit(0.15, "in"),
text_cex = 0.5,
text_pad = unit(0.05, "cm")
) +
ggspatial::annotation_north_arrow(
location = "bl",
which_north = "true",
pad_x = unit(0.27, "in"),
pad_y = unit(0.3, "in"),
height = unit(.8, "cm"),
width = unit(.8, "cm"),
style = north_arrow_fancy_orienteering
)

I am using RStudio 2023.06.0 Build 421
R version 4.3.1 "Beagle Scouts"
and urbnmapr 0.0.0.9002 that I installed 4 July 2023 from github
