[R] asymptote

[Alexy Khrabrov]

I have a graph which looks like hyperbole.  I'd like to fit a  
straight line to the lower segment going to infinity, approaching the  
X axis -- I'm interested in the angle.  If I'd do it manually, I'd  
cut off a certain initial part of the range, [0..x_min], and then do  
an lm with the rest.  Yet I wonder whether those "curve fitting"  
packages mentioned earlier do something similar automatically?

Cheers,
Alexy
