represents a 2 level design with center point.

A list of length 3 character vectors that are the level names of
factors in a design to be checked.

For making Trellis-type conditioning plots without strip labels.
This is useful for displaying the structure of results from factorial designs
and other studies when many conditioning variables would clutter the display
with layers of redundant strip labels. Settings of the variables are encoded by
layout and spacing in the trellis array and decoded by a separate legend. The
functionality is implemented by a single S3 generic strucplot() function that
is a wrapper for the Lattice package's xyplot() function. This allows access to
all Lattice graphics capabilities in the usual way.
