Examples
dsmall <- diamonds[sample(nrow(diamonds), 100), ]

(d <- qplot(carat, price, data=dsmall, shape=cut))
d + scale_shape(solid = TRUE) # the default
d + scale_shape(solid = FALSE)
d + scale_shape(name="Cut of diamond")
d + scale_shape(name="Cut of\ndiamond")

# To change order of levels, change order of
# underlying factor
levels(dsmall$cut) <- c("Fair", "Good", "Very Good", "Premium", "Ideal")

# Need to recreate plot to pick up new data
qplot(price, carat, data=dsmall, shape=cut)

# Or for short:
d %+% dsmall
