[R] Factor Analysis with orthogonal and oblique rotation

[Jeremy Miles]

Varimax is orthogonal, promax is oblique.  Varimax is generally not
recommended.  See: Preacher, K. J., & MacCallum, R. C. (2003).
Repairing Tom Swift's electric factor analysis machine. Understanding
Statistics, 2(1), 13-43.   (Google the title and you'll find a PDF).

The fa() function in the psych package has more flavors of extraction
and rotation.
