In the help for scale_fill_identity, it is written

scale_fill_identity(labels=letters[1:4], guide="tile", name="trt")
This code used to work with ggplot2. However, after updating to the newer
version (version 0.6) and R 2.7.2, I get the following error message:
Error in get("new", env = ScaleIdentity, inherits = TRUE)(ScaleIdentity, :
unused argument(s) (guide = "tile")
If I omit the guide="tile" argument, I still get a tile, but I did like the
option for choosing the grob to use.
How should I go about this?
You can no longer select the geom to use for drawing the legend - it's chosen automatically based on the geoms that you included in the plot. Is there a geom in particular that you don't like the legend for? Hadley
