I try to display coloured rectangles behind symbols in a legend (as a 

> plot(10,10)
> legend("top", c("text","text2"), pch=c(21,22), fill=c("red","green"), 

On the resulting graph, the symbol is not centered upon the coloured 
rectangle. Is there a way to adjust their relative position, so that they are 
centered? Looking through ?legend has not helped me (but I might have missed 
the line where it is explained)...
[R version 2.4.0 (2006-10-03) on linux]

Thanks for any help.

Best regards,
