Sarah has told you how to get from where

However, it is easier to start somewhere
else. The more R way to do what you are
doing is to use a list to put the results
of your regressions into. It is then very
easy to use that list, and it is easier to
keep track
Furthermore, if you want to add lines to a plot, I'd advise against the
curve() function, rather use lines() to add lines (or points() for, well,
points) on a plot.
E.g.,
x - seq(0,10,by=0.025)
y - sin(x)
y2 - cos(x)
plot(x,y,type=l,col=red4,lwd=3)
lines(x,y2)
curve() wouldn't work for this
Yes, David, you are right - I have misinterpreted the result. The.pdf is the

There are many ways to do this, but I think this is mostly a question about
