object |
an object of class sem returned by the sem function. |
digits |
number of digits for printed output. |
startvalues |
if TRUE, start values for parameters are printed;
otherwise, the parameter estimates are printed; the default is FALSE. |
A data frame containing the labelled RAM definition matrix, which is normally just printed.
