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
