Well, the last four are methods for multiple comparisons, not themselves
contrasts! R is a tool within which all of these can be done and
most have been, but it is not a `standard statistics package' and
it does not come pre-packaged for particular fields.
Try looking at the help for aov and the references to its S antecedent.
It's much more powerful than `aov' might suggest to a non-statistician.
