Given the matrices nXm, and jYk, form the super matrix of dimensions (n+j) and (m+k) with with elements x and y along the super diagonal. Useful when considering structural equations. The measurement models x and y can be combined into a larger measurement model of all of the variables. If either x or y is a list of matrices, then recursively form a super matrix of all of those elements.

superMatrix(x,y)

`x` |
A n x m matrix or a list of such matrices |

`y` |
A j x k matrix or a list of such matrices |

Several functions, e.g., `sim.structural`

,`structure.graph`

, `make.keys`

use matrices that can be thought of as formed from a set of submatrices. In particular, when using `make.keys`

in order to score a set of items (`scoreItems`

or `scoreOverlap`

) or to form specified clusters (`cluster.cor`

), it is convenient to define different sets of scoring keys for different sets of items and to combine these scoring keys into one super key.
