Converts a row-order lower-triangular distance matrix to a full symmetric matrix.
lower-triangular distance matrix in row order.
R and S-Plus distance functions such as dist and bcdist return a lower triangular distance matrix in column order. Some other programs, such as EUCLID, return the lower triangular matrix in row order. To use this matrix in R/S-Plus functions, it must be converted from row order to column order.
Full symmetric distance matrix.
