Hi
I just realized that when I use linear regression to draw a line through my data points with something like the following:

abline(lm(y ~ x))

the length of the line is infinite, i.e., the line goes beyond the smallest and the largest data values. This seems not very right to me (not to mention it looks unaesthetic). I do not mean to imply that the straight-line behavior of my system is maintained throughout. I would like to limit the length of this line to the range of my data. However, I have not been able to figure out how to. Very disconcertingly, I found out that all the books that teach statistics using R seem to be drawing such infinite length-lines. I would appreciate any advice or suggestions. Regards,

Tariq
