Michael, 

I have submit a similar case last week to the Bug tracker. Maybe you can raise
that "enhancement request" to "defect"

-----------
The Key function generated by some plot commands should have a ... parameter.
Otherwise, the ... in rlegend is useless, and it would be nice to be able to
suppress the box, for example.

Key = function (x = NULL, y = NULL, lev = c("No Fail", "Fail"), pch = c(16, 1))
{ .. part omitted

    rlegend(x, y, legend = lev, pch = pch, ...) invisible()

}
