geom_sf(): POINT geometry doesn't work with shape names #5808
Description
Hello, in geom_point(), passing shape = 23 or shape = "diamond filled" is the same thing (based on this section from the docs):
library(ggplot2)
library(sf)
#> Linking to GEOS 3.11.2, GDAL 3.7.2, PROJ 9.3.0; sf_use_s2() is TRUE
ggplot(iris, aes(Sepal.Length, Sepal.Width)) +
geom_point(shape = "diamond filled", color = "red", fill = "black")
ggplot(iris, aes(Sepal.Length, Sepal.Width)) +
geom_point(shape = 23, color = "red", fill = "black")
However, with geom_sf(), shape = 23 works fine but shape = "diamond filled" doesn’t work anymore:
# from example of geom_sf()
geo_data <- sf::st_read(system.file("shape/nc.shp", package = "sf"), quiet = TRUE) |>
sf::st_transform(3857)
geo_data$geometry <- sf::st_centroid(geo_data$geometry)
ggplot(geo_data) +
geom_sf(shape = 23, color = "red", fill = "black")
ggplot(geo_data) +
geom_sf(shape = "diamond filled", color = "red", fill = "black")

#> ──────────────────────────────────────────────────────────────────────────────I didn't see anything in the docs of geom_sf() or in the docs section linked above mentioning some differences in shape support between geom_sf() and geom_point(). I did a few tests and it seems this is the case for all shape names, not just "diamond filled".
Tried with ggplot2 3.5.0 and Github version.
Thanks
