Dear Jens,
If you're willing to assume multinormality but don't have in mind a
specific model to estimate, then why not use factanal? The uniquenesses
are estimates of the unreliability of the items.
I hope this helps,
John

Dear John,
Dear Joseph,
Thank you for your quick answers and the pointer to semnet.
I try to clarify on my assumptions:
- yes, I am willing to assume multivariate normality
- no, I don't want to assume a single factor model
- I assume there is an unknown number of factors, and I do not know whi
Dear Jens,
It sounds as if you're postulating a single-factor model underlying the x's
(which is an assumption about the structure of the variables). If that's the
case, then you could either use the factanal function in the stats package
or the sem function in the sem package to estimate the mode
