...here's a small reproducible example:
ddf <- data.frame(x = 1:10, y = 0.4 + 0.6 * (1:10) + rnorm(10))
Thanks Rainer. I did not know about dput(). Here is the data.

Two problems I see. The first is the one described fairly clearly by

Take a look at the examples in ?curve. As suggested by Erik, in the
future please read the posting guide so you can get a more accurate

Hello Dear,
I am trying to plot a function to see a minimum point (actually, using
"optim"). For example,

Thank you for your replies. I figured out that curve has an option of add
which adds it to a previously existing graph.
Thank you,
