biplotSlater2d: Draws Slater's INGRID biplot in 2D.
Description
The default is to use row centering
and no normalization. Note that Slater's biplot is just a
special case of a biplot
that can be produced using the biplot2d function with the arguments
center=1, g=1, h=1. The arguments that can be used in this function
are the same as in biplot2d.
Here, only the arguments that are set for Slater's biplot are described.
To see all the parameters that can be changed see biplot2d.
Usage
biplotSlater2d(x, center = 1, g = 1, h = 1, ...)
Arguments
x
repgrid object.
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).
Slater's biplot uses 1 (row centering).
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.
