makeBlockDiag

A utility function generates block-diagonal matrix of size p by p with blocks B1, B2, ..., Bk. Each block matrix is of size blocksize by blocksize. The off-diagonal elements in block matrix are generated from uniform (min.beta, max.beta). The diagonal elements in block matrix are generated from uniform (1, 1.25).

Large-scale gene expression studies allow gene network construction to uncover associations among genes. This package is developed for estimating and testing partial correlation graphs with prior information incorporated.
