[R] line length in legend

 From the code of legend() the length seems to be hard-wired (seg.len  
= 2). You could copy the code and add this "seg.len" as a free  
parameter in your own custom function. An alternative is to use the  
lattice package which has a size argument for this purpose. See ? 
xyplot in the key section.


Hope this helps,
