[R] plotting confidence intervals

[Greg Snow]

I believe there is a set of options in the ggplot2 package that will create a plot and add the confidence region to it, you will need to look at the documentation for ggplot2, I don't know the details (have not made it that far on my to do list, not anything against the package).
