Cronbach's alpha (standardised: of the correlations)
Explained common variance of the general factor
Guttman's lambda 6
The loadings of the first-order factors on the general factor
The item signs (-1 for a flipped item)
The messages R would print (e.g. for two factors), each once.
The oblimin pattern (the varimax loadings for one factor)
Rows g, F1*, ...; columns total, general, group (NaN for a group with no items)
Omega hierarchical: the share of the total variance due to the general factor
Omega asymptotic: the general factor's share of the common variance
Omega total
The varimax loadings of the first-order minres solution
OptionalphiThe factor correlations (absent for one factor)
The Schmid-Leiman matrix, p rows; columns as slNames
["g", "F1*", ..., "h2", "u2", "p2", "com"]
The warnings R would give (e.g. an ultra-Heywood case, or one factor), each once.
