Ok, I will try that, thanks. BTW, where is this aes_string option documented, sounds useful? How could I do the same thing with facetting? If I want to save something like ". ~ groupVar" as a string in a variable, could I pass it with facet_string to ggplot? But anyway, I would be curious how to do it with qplot. The basic question is: How to pass the string of a variable to a function which is supposed to interpret it. Aka: var <- "magicVar" fun(doSomeMagic(var)) doSomeMagic should then write magicVar at the place.
