c distances between the observed
and prediction sites will also be computed. A new directory is
created within the distance directory, with the name corresponding
to the names attribute for the preds
(e.g. <code>attributes(ssn.object$preds)$names</code>). A sequence of
.RData files is created within this directory, similar to the
structure for the observed sites, except that two objects are
stored for each network that contains <em>both</em> observed and
prediction sites. The letters <code>a</code> and <cod
