varimax: Varimax Rotation

In epca: Exploratory Principal Component Analysis

Varimax Rotation

Description

This is a re-implementation of stats::varimax, which (1) adds a parameter for the maximum number of iterations, (2) sets the default normalize parameter to FALSE, (3) outputs the number of iteration taken, and (4) returns regular matrix rather than in loadings class.

Usage

varimax(x, normalize = FALSE, eps = 1e-05, maxit = 1000L)

Arguments

x	A loadings matrix, with p rows and k < p columns
normalize	logical. Should Kaiser normalization be performed? If so the rows of x are re-scaled to unit length before rotation, and scaled back afterwards.
eps	The tolerance for stopping: the relative change in the sum of singular values.
maxit	integer, maximum number of iteration (default to 1,000).

Value

A list with three elements:

rotated	the rotated matrix.
rotmat	the (orthogonal) rotation matrix.
n.iter	the number of iterations taken.
