Firstly, there is no fa() function in base R. There is one in package psych(), which has a maintainer, etc.
I guess that it is because fa() does a non-orthogonal factor rotation and its print method knows about it, whereas the default print method for loadings assumes that rotations are orthogonal. - Peter D. > On 05 Dec 2014, at 13:28 , Rena Büsch <rena.bue...@gmx.de> wrote: > > Hello, > I am trying a factor analysis via R. > When running the pricipal axis analysis I do get different tables depending > on the print command. > This is my factor analysis: > fa.pa_cor_3_2<- fa(ItemsCor_4, nfactors=3, fm="pa",rotate="oblimin") > > To get the h2 I did the following print command: > print (fa.pa_cor_3_2, digits=2, cut=.3, sort=T) > To just get the loadings I did the following print command: > print (fa.pa_cor_3_2$loadings, digits=2, cutoff=.3, sort=T) > > The result of the first print is the following Eigenvalue-cumulative > variance table: > PA1 PA2 PA3 > SS loadings 20.59 18.16 5.03 > Proportion Var 0.28 0.25 0.07 > Cumulative Var 0.28 0.52 0.59 > > With the second print command I get a different table: > PA1 PA2 PA3 > SS loadings 17.63 15.12 3.14 > Proportion Var 0.24 0.20 0.04 > Cumulative Var 0.24 0.44 0.49 > > The loadings are the same for both commands.
