I've put both the title and keyword placement of the legend into
legend() now, in R-devel. I was unaware of the smartlegend() function
(which is actually in gplots); I've just now added an "inset"
parameter like it has. The specification for the location is slightly
different than smartlegend() uses. Because legend() handles the
second parameter in a strange way and I didn't want to fiddle with
that, I put the specification entirely in the first parameter: you
say you want the legend at one of "bottomright", "bottom",
"bottomleft", "left", "topleft", "top", "topright",
"right", or "center".
This should be downloadable tomorrow from the CRAN mirrors.
