On my R installation (0.62.4) there is no dist() function, so I attach one
possibility.  It provides Euclidean distances only, but it does compute
dist(X, Y) as a matrix, as well as dist(X) as a vector of lower-triangular
values; naturally dist(X, X) gives the full distance matrix of X.

Hope this is useful, Jonathan.
