NA's are *not* finite, we don't know what value they are. Read ?factanal If you specify the model with a formula, you can use the 'na.action' argument to tell it what to do with missing values. Something like, factanal(~ ., data = m1, factors = 3, na.action = na.omit) or do this yourself with factanal(na.omit(m1), factors = 3) HTH G -- %~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~% Dr. Gavin Simpson [t] +44 (0)20 7679 0522 ECRC, UCL Geography, [f] +44 (0)20 7679 0565 Pearson Building, [e] gavin.simpsonATNOSPAMucl.ac.uk Gower Street, London [w] http://www.ucl.ac.uk/~ucfagls/ UK.
