Thanks all of you guys!
Your answers were very useful!
Thanks for the answer John, but I will try to keep the dotplot, but it is
very useful to know both techniques anyway :)
Petr, many thanks for your help, it was just what I needed, btw, the
arrangment based on the median was a headache for me! again, thanks!!!

> geom_dotplot(aes(shape = PRESA),
> binaxis = "y", # which axis to bin along
> binwidth = 0.1, # Minimal difference considered
> stackdir = "center" # Centered

> stat_summary(fun.y = mean, fun.ymin = mean, fun.ymax = mean,
> geom = "crossbar", width = 0.5)
