The direction of the constructs in a grid is arbitrary and a reflection of
a scale does not affect the information contained in the grid.
Nonetheless, the direction of a scale has an effect on inter-element
correlations (Mackay, 1992) and on the spatial representation and clustering
of the grid (Bell, 2010). Hence, it is desirable to follow a protocol to
align constructs that will render unique results. A common approach is
to align constucts by pole preference, i. e. aligninig all positive and
negative poles. This can e. g. be achieved using
If an ideal element is present, this element can be used to identify
the positive and negative pole. The function
align the constructs accordingly. Note that this approach does not always
yield definite results as sometimes ratings do not show a clear
preference for one pole (Winter, Bell & Watson, 2010).
If a preference cannot be determined definitely,
the construct direction remains unchanged (a warning is issued in that case).
