[R] "save scores" from sem

[Joris Meys]

PCA and factor analysis is implemented in the core R distribution, no
extra packages needed. When using princomp, they're in the object.

 pr.c <- princomp(USArrests,scale=T)
 pr.c$scores # gives you the scores

see ?princomp

When using factanal, you can ask for regression scores or Bartlett
scorse. See ?factanal.
Mind you, you will get different -i.e. more correct- results than
those obtained by SPSS.

I don't understand what you mean with scores in the context of
structural equation modelling. Lavaan is unknown to me.

Cheers
Joris
