    <p>The values in <code>x</code> are filled into the lower triangular part of a square matrix with the appropriate dimensions (which are determined based on the length of <code>x</code>). If <code>diag=TRUE</code>, then <code>x</code> is assumed to also contain the diagonal values of the lower triangular part of the matrix. If <code>corr=TRUE</code>, then the diagonal of the matrix is replaced with 1'
