These functions implement logical tests for networks' classes.
is_manynet() marks a network TRUE if it is compatible with {manynet} functions.
is_edgelist() marks a network TRUE if it is an edgelist.
is_graph() marks a network TRUE if it contains graph-level information.
is_list() marks a network TRUE if it is a (non-igraph) list of networks, for example a set of ego networks or a dynamic or longitudinal set of networks.
is_longitudinal() marks a network TRUE if it contains longitudinal, panel data.
is_dynamic() marks a network TRUE if it contains dynamic, time-stamped data
All is_*() functions return a logical scalar (TRUE or FALSE).
