[R] text command - how to get a white background to cover grid lines

For posterity, I found the TeachingDemos::shadowtext option most
agreeable for this problem:

    * legend puts a large box around the text which did not seem
possible to shrink, and does not accept vector x, y arguments
    * plotrix::boxed.labels did not work with pos=4 (this moved the
text, but not the box)
    * TeachingDemos::shadowtext puts an opaque "shadow" around the
text, rather than a box, which obscures a minimum of background while
still making the labels readable. col="black", bg="white" options
produced this effect (default options are opposite this).
