[R] In factor analysis in the psych package, how can I work out which factors the columns in $scores relate to? How do I know what each of the scores is scoring?

[Brent Caldwell]

Hi
I have used fa() to perform a factor analysis of a psychological battery which is thought to have 11 factors.  I can identify which factors the loadings relate to easily enough because I can see which items are loading onto each of the columns in the $loading output.  However, how can I identify which items or loadings are being used to create each of the columns in the $scores output?  I have used generalised linear models which have shown that some of the scores are significant predictors of treatment outcome, but I can't work out which of the 11 factors they are scoring?

when I export to csv the $loadings I get the following columns in this order:
 MR4, MR3, MR2, MR6, MR7, MR5, MR1, MR8, MR10, MR9, MR11 

When I export to csv the $scores I get the following columns in this order:
V1, V2, V3, V4, V5, V6, V7, V8, V9, V10,V11 

Are the scores in the column V1 derived from the loadings in column MR1 ?  
Or are the scores in the first column of $scores (ie V1) derived from the loadings in the first column of $loadings (ie MR4)?

Thank you very much for your guidance, and your patience with my confusion
Best wishes
Brent
