# Plot an eigenstructure analysis (ESA) in 2D grid with 3D impression (pseudo 3D).

Source:`R/repgrid-plots.r`

`biplotEsaPseudo3d.Rd`

The ESA is
a special type of biplot suggested by Raeithel (e.g. 1998).
It uses midpoint centering as a default. Note that the eigenstructure analysis
is just a special case of a biplot that can also be produced using the
`biplot2d()`

function with the arguments
`center=4, g=1, h=1`

.
Here, only the arguments that are modified for the ESA biplot are described.
To see all the parameters that can be changed see `biplot2d()`

and `biplotPseudo3d()`

.

## 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). Eigenstructure analysis uses midpoint centering (

`4`

).- g
Power of the singular value matrix assigned to the left singular vectors, i.e. the constructs. Eigenstructure analysis uses

`g=1`

.- h
Power of the singular value matrix assigned to the right singular vectors, i.e. the elements. Eigenstructure analysis uses

`h=1`

.- ...
Additional parameters for be passed to

`biplotPseudo3d()`

.
