there are inconsistencies in the documentation and execution of a model involving dimnames for matrices
i read in an observed cov matrix using read.table(..., header=TRUE, ...) and got this error in mxRun:
>Error: The dataset associated with the ML objective in model 'MZ' does not contain identical row and column non-NULL dimnames.
fine. fixed that up, and the next mxRun gave this error:
>Error: The expected covariance matrix associated with the ML objective in model 'MZ' does not contain dimnames.
the documentation does not mention that an MxData object of type='cov' (and possibly 'corr' and 'sscp') requires identical row and column names. documentation in mxAlgebra implies that dimnames is initialized as NA.
