[R] Help with beanplot fromatting

[Uwe Ligges]

Easiest way is probably to make grouprep a factor and insert a level 
without observations such as in:

mydata$grouprep <- factor(mydata$grouprep, levels =
   paste(rep(LETTERS[1:5], each=2), paste("grp", 1:2, sep="")))
beanplot(val~grouprep, data = mydata, ll = 0.04,
   main = "example", ylab = "Size", xlab = "tank",
   side = "both",  border = NA,
   col = list(c("blue", "white"), c("red", "yellow")))
