[R] OS X, exporting graphics, postscript()

[Jason Miller]

R users,

OK, so I feel dumb.  I didn't understand that dev.off() turns off the 
process of writing a file, and that I can't open a file until dev.off() 
is called to complete the file.

Thanks to everyone who responded to my call for help.

I'm really liking what I'm learning about R.  I hope to learn enough to 
teach my colleagues and students about it.

Jason
