Description Usage Arguments See Also Examples
Draw the Slater's INGRID biplot in rgl (3D device).
The 3D biplot opens an interactive
3D device that can be rotated and zoomed using the mouse.
A 3D device facilitates the exploration of grid data as
significant proportions of the sum-of-squares are often
represented beyond the first two dimensions. Also, in a lot of
cases it may be of interest to explore the grid space from
a certain angle, e.g. to gain an optimal view onto the set
of elements under investigation (e.g. Raeithel, 1998).
Note that Slater's biplot is just a special case of a biplot
that can be produced using the biplot3d
function with the arguments center=1, g=1, h=1
.
1 | biplotSlater3d(x, center=1, g=1, h=1, ...)
|
x |
|
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).
Default is |
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. |
