Example ?ggbeeswarm does not work (again)

[George Moroz]

Like in #30.

library(ggplot2)
library(ggbeeswarm)

ggplot2::qplot(class, hwy, data = ggplot2::mpg, position = position_quasirandom())

distro <- data.frame(
  'variable'=rep(c('runif','rnorm'),each=100),
  'value'=c(runif(100, min=-3, max=3), rnorm(100))
)
ggplot(distro,aes(variable, value)) +
  geom_beeswarm(priority='density',size=2.5)
