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":
http://cran.r-project.org/doc/manuals/R-intro.pdf
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:
http://cran.r-project.org/doc/Rnews/Rnews_2003-2.pdf
Notwithstanding all of that, searching the r-help archives is yet
another terrific online (and free) resource that you _should_ avail
yourself of.
HTH,
