New in data representation and using ggplot2
I plotted data using boxplot like this
p <- ggplot(data, aes(x, y, colour=foo, fill=bar))
p + geom_boxplot()
data my data_frame
x is a 3 level factor
y is numeric (obviously)
foo is a 2 level factor
bar is a 3 level factor
So I have 3 * 2 * 3 = 18 boxplots (18 levels) from 3 different factors
On data I have an other column with mostly NA and sometime the duplicated y value, let's call it y_special (Before I had just TRUE marker instead of a duplicated value in this column, but I later assumed it will be easier to plot it that way)
I would like to plot y_special with geom_point on top of the corresponding boxplot
