[R] Plot labeling question

[Paul, David A]

I have an older Splus script that generated some 
regression graphics for me.  In it, I used the commands

key(10,800,text="<blah1>",border=0)
key(10,750,text="<blah2>", border=0, background = 9)
text(locator(1),"95% Confidence Limits")
locator(n=2,type="l")
text(locator(1),"Model for Group 1")
locator(n=2,type="l")

There is no "key" function available in R; is there an 
equivalent that I can use?


Much thanks in advance,

 David Paul
