[R] ggplot2 boxplot points (size,color,shape)

[Thierry Onkelinx]

You need to set the shape manually

library(ggplot2)
n <- 200
dataset <- data.frame(
  Type = sample(c("A", "B"), n, replace = TRUE),
  Value = rnorm(n)
)
ggplot(dataset, aes(x = Type, y = Value)) + geom_boxplot() +
geom_jitter(aes(shape = Type)) + scale_shape_manual(values = c(1, 19))

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
~ John Tukey
