Scale for shapes, aka glyphs.


scale_shape(..., solid = TRUE)


common discrete scale parameters: name, breaks, labels, na.value, limits and guide. See discrete_scale for more details
Are the shapes solid, TRUE, or hollow FALSE?


A continuous variable can not be mapped to shape.


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
