Converts a symmetric distance matrix to a column order lower triangular matrix.
lower(m)a symmetric distance matrix.
a column order lower triangular matrix.
Converts a symmetric matrix, for example a dissimilarity matrix, into a lower- triangular matrix. This may be useful to format the input for certain clustering and ordination functions. Note that lower() used on a 1x1 matrix will return the single element, which may not be the correct behavior in all cases, while full() used on a single element will return a 2x2 matrix.
