biplotSlater3d | R Documentation |
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
.
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. |
