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?
Dan

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.

After that, type: RSiteSearch("legend margin") Currently, the fourth entry shows a solution: http://finzi.psych.upenn.edu/R/Rhelp02a/archive/67979.html Uwe Ligges> Dan >
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).
