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).
is_manynet(.data)
is_graph(.data)
is_edgelist(.data)
is_list(.data)
is_longitudinal(.data)
is_dynamic(.data)An object of a manynet-consistent class:
matrix (adjacency or incidence) from {base} R
edgelist, a data frame from {base} R or tibble from {tibble}
igraph, from the {igraph} package
network, from the {network} package
tbl_graph, from the {tidygraph} package
TRUE if the condition is met, or FALSE otherwise.
