alignByIdeal: Align constructs using the ideal element to gain pole...

In OpenRepGrid: Tools to Analyze Repertory Grid Data

Align constructs using the ideal element to gain pole preferences.

Description

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 constructs by pole preference, i. e. aligning all positive and negative poles. This can e. g. be achieved using swapPoles. If an ideal element is present, this element can be used to identify the positive and negative pole. The function alignByIdeal will 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).

Usage

alignByIdeal(x, ideal, high = TRUE)

Arguments

x	repgrid object
ideal	Number of the element that is used for alignment (the ideal).
high	Logical. Whether to align the constructs so the ideal will have high ratings on the constructs (i.e. TRUE, default) or low ratings (FALSE). High scores will lead to the preference pole on the right side, low scores will align the preference pole on the left side.

Value

repgrid object with aligned constructs.
