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.
Regards,
Tena Sakai

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.
