Thanks!

I realized the datasets were not available, but not that they were in a
separate package. I have never had to load this package in previous versions
and assumed they were part of one of the default main packages.

An easy fix was to adjust my default packages in the Rprofile file to
include "datasets"

This is for those who don't know a file in the etc directory.

options(defaultPackages=c("utils" ,"datasets", "graphics" ,"stats", "methods", "MASS", "gtools"))

Not sure how this happened as I never had to do this before.

For some reason you do not have the datasets package attached.

> find(Indometh)

[1] "package:datasets"

> find(volcano)

[1] "package:datasets"
