That seem to have been the issue. By upgrading to the most recent update in the repository, I have been able to plot both the histogram and the line, each from a different dataset. As a side note, it appears that ggplot2.aes_string is now ggplot2.aes, which is the way it is in R. Next problem: Because I included the option y='..density..' in my histogram aes, my plot now has ..density.. as its x label. This doesn't happen in R. I thought I could rectify this by adding the line pp=pp+ggplot2.opts(xlab="z"), but that doesn't seem to work. If I remove the option y='..density..' from my histogram aes, I get z as my x label, but I still cannot change it using the options (e.g. pp=pp+ggplot2.opts(xlab="z position") has no effect). Any thoughts? Faisal ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
