Converts a column order distance matrix to a full symmetric matrix.
lower-triangular column order distance matrix.
Converts lower-triangular distance matrix as written by R/S-Plus functions into a symmetric matrix. 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.
a full symmetric matrix.
