Hi, > What device are you using to plot the graph?
I am not explicitly specifying any. I am on redhat linux and as I understand it R uses DISPLAY environment variable, which is set for an X11 server (X Darwin, v1.4.0, X11 6.8.2). Other qplot()'s I have used (straight out of the book) work fine. I am coming to believe that before the current incarnation, it simply ignored the alpha parameter and gave the plot, whereas with the latest it doens't want to ignore and not going further. I'd be curious if this problem is reproducible with anybody else.

What device are you using to plot the graph? According to the warning, the device is causing the problem.

Hi Ian, Per your suggestion, I reinstalled R 2.9.0, then I reinstalled ggplot2 on top. The problem persists. Here's the what happens after the installation: > qplot (carat, price, data = diamonds, alpha = I(1/10)) Warning message: In grid.Call.graphics("L_points", x$x, x$y, x$pch, x$size) : semi-transparency is not supported on this device: reported only once per page The entire record of installing ggplot2 package, ending up with the line above is in the attached file. I would think this should be reproducible with anybody else. If you have any other suggestion, I am all ears.

Tena, May I suggest that you do a full clean install of R 2.9.0, then install ggplot2 from cran. See if the problem persists after that.
