Distance matrix conversion

Description

Converts a row-order lower-triangular distance matrix to a full symmetric matrix.

Usage

1

Arguments

v

lower-triangular distance matrix in row order.

Details

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.

Value

Full symmetric distance matrix.
