R help - Aug 2002 - legend() outside plotting region

Hi,

Is it possible to put the legend outside the plotting region?

Say, I have some 24 lines within my plot, which pretty much filled the
plotting region and left me no space (well not enough space) to put in a
legend.  So I'd like to put the legend outside the plotting region
(i.e. the region enclosed by the two axis -- I hope I got my terminology
right).

Actually, I did the 24 lines with something like:
 for(i in 1:ncol(FOO))
     lines(FOO[, i], lty = i)
where FOO is my data frame containing 24 columns.  As a side track, is
there a better way to represent this, as 24 lines is very difficult to
distinguish anyhow.  This data frame, by the way, is a time series.

Cheers,

Kevin

After you have plotted the data, use

par(xpd=T)

and then legend() with x,y values where you want it.

24 lines would probably confuse the average spider. What do you want to 
illustrate? If it is a comparison between one group of lines and another, 
you might be able to plot two polygons showing the region that each group 
occupies, or something like that.
