 Hi all,
 Another plotting question I am afraid.  Is there anyway of putting a
 legend for a plot in a margin rather than within the figure.  I am
 trying to plot a 3x2 plot and I want to have:
 1) One key along the bottom for all the plots
 2) A label (a,b,c) for each plot (see previous emails)
 
 Is there any websites etc. that explain this sort of thing?

Please read the posting guide.

After that, type:
   RSiteSearch(legend margin)

Currently, the fourth entry shows a solution:

Thanks.  That got me onto the right track.  Because it is a multiplot
and I wanted it along the bottom, I found that I had to use par(xpd=NA)
and then position it relative to the last of the multiplots.  After a
bit of trial and error I got there.

Thanks

Re: [R] Plot legend in margin

2007-08-10 Thread Greg Snow 
Another couple of things to think about:

You could use the layout function to set up your multiple plots and
include an extra plotting area at the bottom to place the legend in.

If you stick with the solution below then the cnvrt.coords function from
the TeachingDemos package may be useful (will help you find the
coordinates relative to the last plot).

Hope this helps,
