How to add label to lines()

I am plotting a number of lines on a standard plot.  I would like to  
add labels at the end (rhs) of each line.  is there a way to do this  
other than defining the individual xy coordinates and placing each  
label using text()

Without an example it is difficult to know if your coding is  
efficient. The text fn is vectorized, so there may be a one-liner that  
does what you could be currently doing piecemeal.

plot(1,1)
  for( b in 1-(1:5)/20) abline(a=0,b=b)
  text(1.4, 1.4*(1-(1:5)/20), as.character(1-(1:5)/20) )
