the matrix to be filtered
A single row or single column R matrix indicating which values should be filtered from the mxMatrix.
omxSelectRowsAndCols, omxSelectRows, and omxSelectCols returns the filtered entries in a target matrix specified by a single row or single column selector matrix. Each entry in the selector matrix is treated as a logical data indicating if the corresponding entry in the target matrix should be excluded (0 or FALSE) or included (not 0 or TRUE). Typically the function is used to filter data from a target matrix using an existence vector which specifies what data entries are missing. This can be seen in the demo: RowObjectiveFIMLBivariateSaturated.
Returns a new matrix with the filtered data.
The function is most often used when filtering data for missingness. This can be seen in the demo: RowObjectiveFIMLBivariateSaturated. The OpenMx User's guide can be found at http://openmx.ssri.psu.edu/documentation. The omxSelect* functions share some similarity to the Extract function in the R programming language.
