Applying this methodology to the different classes of nectarines
(two classes: organic vs. conventional) and peaches (four classes:
organic vs. conventional vs. platters vs. orchards) we found a good
class prediction (Fig. 5): a good separation of the two types of
nectarines was obtained (Fig. 5.1) and especially, it was found that
conventional fruits were most distinguishable from other types
(Fig. 5.2), as previously mentioned for the analysis of yeast ecology
of peaches.
