[R] Legend - revisited

[Monica Palaseanu-Lovejoy]

Hi,

I am trying to put a legend to a graph of quintiles. The points for 
quintiles are colored differently and the points themselves have 
different sizes. I was able to match everything but the points sizes. 
If i am using cex parameter it changes both the points and the text 
dimensions .... 

I am not sore if i was clear, but what i want is different sizes for the 
points but same size for the text in the legend. Here it is the 
command i am using:

legend(438000, 367000, c("1st quintile", "2nd quintile", "3rd 
quintile", "4th quintile", "5th quintile"), pch = c(21,21,21,21,21), 
pt.bg = c("blue", "green", "yellow", "brown", "red"), cex=1.2)

Any suggestion will be greatly appreciated.

Monica
