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()
