The key matrix is used to specify any number of weighted item composites. A correlation matrix of these composites and the original correlation matrix is then computed and returned.

1	fuseMat(r_mat, wt, type = "full")

`r_mat`	A correlation matrix.
`wt`	A matrix with one row for each composite and one column for each item contained in `r_mat`. The value if each element corresponds to the weight given to an item.
`type`	The type of output desired.

If type = "cxc" then a matrix of the intercorrelations between the specified composites are returned. If type = "full" then all the intercorrelations between both the original items and the specified composites are returned.
