I am attempting to create a notched boxplot in ggplot2, thus:
m <- ggplot(dat, aes(y = Slope, x = factor(BB),
fill=factor(BB)))
m + geom_boxplot(notch = TRUE)
However the plot produced is just a normal boxplot without notches. Has anyone encountered this issue before? Is there a way around it? I'm not sure if i'm missing something really obvious here!
I cna't put my own data up but I am getting the same result with the example dataset from ggplot2:
p <- ggplot(mtcars, aes(factor(cyl), mpg))
p + geom_boxplot(notch = TRUE, notchwidth = .3)

I suppose that your problem is because you are using an older version of ggplot2. Noting @joran's comment, I'd also recommend to update R first before updating packages.
Then, you can install/update ggplot2
and all its dependencies by:
install.packages("ggplot2", dependencies = TRUE)
Hope this helps.
