Residuals in the various psych functions are extracted and then may be "pretty" printed.

residuals(object,diag=TRUE,...)
## S3 method for class 'psych'

Arguments

• object: The object returned by a psych function.
• diag: if FALSE, then convert the diagonal of the residuals to NA

sum(residuals(f3)^2) #include diagonal
sum(residuals(f3,diag=FALSE)^2,na.rm=TRUE) #drop diagonal
