# biplotSlater2d: Draws Slater's INGRID biplot in 2D. In markheckmann/OpenRepGrid: Tools to Analyze Repertory Grid Data

## 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

 `1` ```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. `...` Additional parameters for be passed to `biplot2d`.
