   I have a set of 4 graphs and I need to add a legend
that is shared by those 4 graphs. This is what I

>locator(1) # I placed the cursor in the center of the
4 graphs
[1] 9.299001

[1] 226.3201

>legend(9.3,226.3,"and the rest of the legend
arguments")# but the legend didn't show.

    The legend only appears when I place in inside any
of the for plots. How can I place it outside these
plots, in the center.

   Your help will be very much appreciated.
