clip to keep coordinate system?

dear R wizards:

plot( 1, 1, ylim=(2,10), xlim=(2,10), type="n");
rect( -1, -1, 12, 12, col=gray(0.99) );

unfortunately wipes out the border axes around the plot.  how do I keep
this?

I think you meant
   plot( 1, 1, ylim=c(2,10), xlim=c(2,10), type="n")
   rect( -1, -1, 12, 12, col=gray(0.99) )
Your code has two syntax errors and two spurious semicolons.

The border axes are gone because you have drawn on top of them.

On the quartz() and pdf() devices you could draw the rectangle in a 
partially transparent color rather than solid light grey.

More generally, you can redraw the border axes with box()

Dear wizards:

despite my omission of the c() on the limits, a kind soul sent me the 
answer: a par(new=T) will make the next plot() redraw nicely.

a help question for  R-2.1.0:  help.search("transparent")  gives
"No help files found with alias or concept or title matching 
'transparent' using fuzzy matching."
but "?par" has the word transparent in the color specification section 
(though an example of usage would make this one much clearer, too).  
shouldn't help.search() look through the build-in docs, too?

sincerely, /iaw

What's wrong with the semicolons? Technically, they're not necessary,
but they definitely improve readability without doing any harm.
