Describing the topology of networks of seed circulation is interesting since it gives insight on how exchanges are organized within a PPB programme or a Community Seed Bank[@bioversity_csb_2015][@pautasso_seed_2013]. Analysis can be done at several geographical or organizing scales, for example local, regional or national.
Two types of network are handled within PPBstats
:
unipart network where nodes are:
bipart network where nodes are either location or germplasm
PPBstats
regarding network analysisThe workflow is very simple as only descriptive analysis can be done based on network format (Figure \@ref(fig:decision-tree-Study-network-of-seed-circulation)).

Figure \@ref(fig:main-workflow-network) displays the functions and their relationships. Table \@ref(tab:function-descriptions-workflow-network) describes each of the functions.
You can have more information for each function by typing ?function_name
in your R session.
Note that plot()
is S3 method.
Therefore, you should type ?plot.PPBstats
to have general features and then see in details for specific functions.
