[R] ggplot: dodge positions

[Thaler,Thorn,LAUSANNE,Applied Mathematics]

Yes indeed. Sorry for the typo, I just added the library(ggplot) thing afterwards and I did not check for the spelling. So it should read as library(ggplot2) and there the issue is still unsettled.

Thx for pointing that out.
