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?

Subject: [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?

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
