Summary of model object

Transforms coefficients into a standardized factor loading's metric. For MixedClass objects, the fixed and random coefficients are printed.

## S4 method for signature 'SingleGroupClass'
summary(object, rotate = "oblimin",
  Target = NULL, suppress = 0, digits = 3, verbose = TRUE, ...)

`object`	an object of class `SingleGroupClass`, `MultipleGroupClass`, or `MixedClass`
`rotate`	a string indicating which rotation to use for exploratory models, primarily from the `GPArotation` package (see documentation therein). Rotations currently supported are: `'promax'`, `'oblimin'`, `'varimax'`, `'quartimin'`, `'targetT'`, `'targetQ'`, `'pstT'`, `'pstQ'`, `'oblimax'`, `'entropy'`, `'quartimax'`, `'simplimax'`, `'bentlerT'`, `'bentlerQ'`, `'tandemI'`, `'tandemII'`, `'geominT'`, `'geominQ'`, `'cfT'`, `'cfQ'`, `'infomaxT'`, `'infomaxQ'`, `'mccammon'`, `'bifactorT'`, `'bifactorQ'`. For models that are not exploratory this input will automatically be set to `'none'`
`Target`	a dummy variable matrix indicting a target rotation pattern. This is required for rotations such as `'targetT'`, `'targetQ'`, `'pstT'`, and `'pstQ'`
`suppress`	a numeric value indicating which (possibly rotated) factor loadings should be suppressed. Typical values are around .3 in most statistical software. Default is 0 for no suppression
`digits`	number of significant digits to be rounded
`verbose`	logical; allow information to be printed to the console?
`...`	additional arguments to be passed
