Add geom_stars for ggplot plotting

[adrfantini]

A while back sf has implemented a geom_sf which provides a ggplot2 plotting interface for sf objects. And it is awesome.

stars imho should also provide something similar.

is there a way geom_stars() could actually plot a color composite?

st_as_stars(L7_ETMs)[,,,1:3] |> st_rgb() -> x
ggplot() + geom_stars(data = x, fill = as.vector(x[[1]]))

Cool. I suggest including this example in the documentation, perhaps with linear stretching.

Done; the linear stretching is in the docs of st_rgb().
