[R] legend of maps generated by function symbols

[Marion Jacquot]

I generated maps with the function symbols (graphics). These are basic 
maps generated with :

symbols(x,y,circles=myvariable)

where x et y are spatial coordinates corresponding to replicates of 
"myvariable".

I would associate legend to this kind of maps, is it possible?

Regards,
Marion.
