procrustes performs procrustes rotation, at the moment only of unfold solutions.
## S4 method for signature 'unfolding'
procrustes(x, use=attr(x,"procrustes_use"), target, ...)
an object the components of which to rotate.
which of the components of x should be used as criterion for rotation.
a matrix to which the rotation criterion should be brought as close as possible.
further arguments for future methods, currently ignored.
a copy of x with components appropriately rotated.
