Changes in version 2007.06-1 (2007-06-07) o fixed a couple of lingering $Lh (in print and summary methods) that should have been changed to $loadings. Changes in version 2007.04-1 (2007-04-23) o removed an extra comma in c() that caused a test failure with R-2.5.0 o added eiv rotation. o renamed $Lh in the result from GPForth and GPFoblq to $loadings. As a result, rotation methods calling these function no longer need to rename this element in order to work with factanal and other programs.
