My practice is to write the script and run it using the 'source()' function. What's weird is that the resultant figure is not readable by OS X 10.7.0 (Lion). While trying to figure out what I did wrong, I discovered that typing the exact same code into the R prompt (running in Terminal) will produce the figure as I would expect it. The only idea I have is that something has changed in Lion that doesn't allow 'source()' to interpret it properly.

I don't have Lion, but it would be helpful to know what "not readable" 
means.  If you try to open the file in Preview, what happens?
