Plausible. Or it could be 30-40 arbitrary pairings with no variable used twice. ggplot: came for the Tufte-type aethestic, stayed for the graph grammars. I have a lot more experience with ggplot than base&lattice since I switched so early but wiser heads tell me that they are similar in capability. I just find ggplot easier to work with and look at.
