R help - Mar 2015 - ggplot2 boxplot points (size,color,shape)

Hi,

I am trying to create a boxplot (with geom_jitter) such that the points
from one set of values are shown as circles, and the second set of points
also as circles, but with no fill. In other words, how can I control the
shape and color for the points appearing in this boxplot?

======library(ggplot2)

myvect1 <- rnorm(100)
myvect2 <- rnorm(100)

fill1 <- rep('solid',100)
fill2 <- rep('solid',100)

myvect <- c(myvect1,myvect2)
myfill <- c(fill1,fill2)

mydat <- data.frame(myvect,myfill)

## How can I control the shape, color of the points in the boxplot based on
the values of myfill?
ggplot(data=mydat,aes(x='test',y=myvect)) + geom_boxplot() +
geom_jitter()

=========
thanks!!

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))

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 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.
