By default all of the components present in the loadings are rotated,
though scores are only rotated when enough information for rotation is
available.

In the case of a
"princomp"
object, the
sdev
component has elements
turned to
NA
since the component is not very meaningful after rotation.
Rotations generally assume that there are more rows than columns in the
matrix.
The
scores
argument to
princomp
is useful if rotation of principal
components is intended.
