Dan,

Do not edit the barplot() code. Use the legend() function instead, which
enables you to specify the x,y coordinates of the upper left hand corner
of the legend box. See ?legend

A fair number of the questions that you have had regarding graphics are
covered in Chapter 12 "Graphical Procedures" in "An Introduction to R":

which is included with the R installation.

Another online resource for some graphics assistance would be R News
Volume 3 Number 2 for October 2003, which has an article on R's base
graphics in the R Help Desk section:

Notwithstanding all of that, searching the r-help archives is yet
another terrific online (and free) resource that you _should_ avail
yourself of.

HTH,
