dear userR: I am trying to plot two dependent variables in the same plot in ggplot2. because these two variables have very different magnitude, I have to use a second Y axis. I hope one variable to be line and the other to be barchart. The x axis is continuous. Yet since I have to make barchart, I guess I have to treat it as discrete or categorical. I have been google searching for the whole afternoon but do not have any clue. Can anyone give me a direction (not have to be a complete answer...)?
Hi xin wei, If you're desperate, have a look at twoord.plot in the plotrix package. Jim
