[R] Factor Analysis with orthogonal and oblique rotation
Hello I seem to find only two types of rotation for the factanal function in R, the Varimax and Promax, but is it possible to run a orthogonal and oblique rotations in R? Thanks in advance Rosario

[R] Factor Analysis with orthogonal and oblique rotation
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.
