True, AFAIK, in the strict sense.  However, quite a few books
call factor analysis what statisticians call principal components
analysis, and that is there, in standard package mva.

I have an experimental implementation, but it depends on features in the
development version, due out as 0.99.0 next week. However, people
seem to expect things such as varimax rotations to go with factor
analysis, and I have not yet thought about that.

My feeling is that there are plenty of packages that do factor analysis,
and not much demand for it in R.  Anyone want to write a factor analysis
package for R?
