[R] plotting confidence intervals

[Erin Hodgess]

Hi R People:

If I have a fitted values from a model, how do I plot the
(1-alpha)100% confidence intervals along with the fitted values,
please?

Also, if the intervals are "shaded" gray, that would be nice too, please?

I check confint, but that doesn't seem to do what I want.

Thanks in advance,
Sincerely,
Erin
