[R] plotting confidence intervals

[Daniel Malter]

Erin and all, I lavishly used the factor 2 for the confidence intervals. Of
course this should be approximately 1.96 for the 95% CI under the assumption
of normality. So just adjust the factor accordingly or according to your
desired alpha level when you create the CI data frame. Otherwise, my example
should be fine.

Betreff: [R] plotting confidence intervals

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
