Order grid by angles between construct and/or elements in 2D.
The approach is to reorder
the grid matrix by their polar angles on the first two principal
components from a data reduction technique
(here the biplot, i.e. SVD). The function
reorder2d
reorders the grid according to the angles
between the x-axis and the element (construct)
vectors derived from a 2D biplot solution.
This approach is apt to identify circumplex
structures in data indicated by the diagonal stripe
in the display (see examples).

dim |
Dimension of 2D solution used to calculate angles
(default |
center |
Numeric. The type of centering to be performed.
0= no centering, 1= row mean centering (construct),
2= column mean centering (elements), 3= double-centering (construct and element means),
4= midpoint centering of rows (constructs).
The default is |
normalize |
A numeric value indicating along what direction (rows, columns)
to normalize by standard deviations. |
g |
Power of the singular value matrix assigned to the left singular vectors, i.e. the constructs. |
h |
Power of the singular value matrix assigned to the right singular vectors, i.e. the elements. |
rc |
Logical. Reorder constructs by similarity (default |
re |
Logical. Reorder elements by similarity (default |
