R help - Oct 2009 - How to create a legend that automatically reads the values from two vectors?

Hi all!!!

How can I create a legend to my plot that automatically reads the values
from two vectors?
betav<-c(0.78,0.94,0.88,0.41,0.59,4.68)
etav<-c(235.6,59.5,31.2,8.7,3.2,1174)
 I want my legend to show 6 lines
beta(in greeks)=0.78,eta(in greeks)=235.6
beta(in greeks)=0.94,eta(in greeks)=6.59
....
beta(in greeks)=4.68,eta(in greeks)=1174

I know how to do it "by hand" but I have to write them one by one and
this
is not efficient. How can I do that? I guess it has to be with the lapply or
rapply functions, but I can't really get it!!!!


Many thanks in advance

Best regards

Javier

Hi Javier,
Maybe not exactly what you want, but try:

addtable2plot(2,8,rbind(betav,etav),bty="o",
  display.colnames=FALSE,display.rownames=TRUE)

using your own x and y coordinates, of course. addtable2plot is in the 
plotrix package.
