don't use the type argument.  You are telling plot to plot points.
also please use dput() to make example code that can be cut and pasted
out of the email right into R, so that your problem is reproducible.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
