It depends on what you are after.  I am by no means a wunderkind when
it comes to transformation, but in the package vegan type
?wisconsin
and that should give you a start,  but if you know what
transformations you would like to preform then apply should do what
you need with whatever transformation you are trying to use.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
