Arguments
- ...

,limits
andguide
. Seediscrete_scale
for more details- solid
Are the shapes solid,
TRUE
, or hollowFALSE
?
Examples
dsmall <- diamonds[sample(nrow(diamonds), 100), ]
(d <- ggplot(dsmall, aes(carat, price)) + geom_point(aes(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
ggplot(dsmall, aes(price, carat)) + geom_point(aes(shape = cut))
# Or for short:
d %+% dsmall
