You're missing one thing. You want: layer(data = somdf, geom = "tile", aes(fill=rgb)) (i.e. there's an aes function wrapped around the fill). I'd probably use a few more of the built in defaults to get: geom_tile(aes(fill = rgb)) > The other issue I'm having is that the above seems to create multiple > plots, another, apparently identical, plot gets drawn after I call > dev.off(). I have no idea why this would be so.
