Promax.only: Promax rotation (without prior Varimax rotation)

In HDMD: Statistical Analysis Tools for High Dimension Molecular Data (HDMD)

Description

Promax.only is an oblique rotation of factor loadings. This function is directly derived from the Promax function in the psych package, but only performs the promax rotation without first specifying a varimax orthogonal rotation. Further specifying the power of the fitting function allows for greater versatility.

Usage

Promax.only(x, m = 4, rotate.structure=NULL)

Arguments

x	matrix of factor loadings
m	power of fitting function
rotate.structure	rotation matrix if loadings have been prerotated. Default is the identity matrix.

Details

An oblique factor rotation will rescale the loadings with factors having correlated structure Phi

Value

loadings	Oblique factor loadings
rotmat	Rotation matrix structure. If rotated.structure supplied, it will be factored into rotmat.
Phi	Correlation matrix structure of Factors

Note

Adapted directly from Promax of the psych package
