## Not run:
colour <- c("red","green","blue","yellow")
qplot(1:4, 1:4, fill=colour, geom="tile")
qplot(1:4, 1:4, fill=colour, geom="tile") + scale_fill_identity()
# To get a legend, you also need to supply the labels to
# be used on the legend
qplot(1:4, 1:4, fill=colour, geom="tile") + scale_fill_identity(labels=letters[1:4], name="trt")
# cyl scaled to appropriate size
qplot(mpg, wt, data=mtcars, size = cyl)
# cyl used as point size
qplot(mpg, wt, data=mtcars, size = cyl) + scale_size_identity()
