Verify a Dynamically Extended Network Object
Checks a networkDynamic object for any activity information that is not correctly specified.
network.dynamic.check(x, verbose = TRUE, complete = TRUE) is.networkDynamic(x)
x |
an object, hopefully of class |
verbose |
logical; should output messages be printed to the user? |
complete |
logical; should a complete test be ran, including checks of the activity matrices for edges and vertices, versus a check of only edge activity invovling non-active vertices |
Currently, network.dynamic.check runs three types of checks on an input object:
If a complete test is run, vertex spell matrices and edge spell matrices (if any) are checked for legality, specifically these are checked for correct dimensionality and proper spell ordering.
If vertex and edge spell matrices are correctly specified or
assumed to be using complete=FALSE, incident vertices of
active edges (if any) are checked to ensure that they are also
active during the specified period(s).
If a complete test is run, and any TEA attributes are attached to the network, vertices or edges, they will be checked for correct structure.
If spell matrices are only acted upon by network or networkDynamic methods, there is no need to run a complete test - correct dimensionality and spell ordering are guaranteed.
is.networkDynamic checks if its argument has the class 'networkDynamic'.
For network.dynamic.check: A list of logical vectors, one for
each network component checked:
$vertex.checks : Whether the spell matrix of each vertex (if any)
is correctly specified
$edge.checks : Whether the spell matrix of each edge (if any)
is correctly specified
$dyad.checks : Corresponding to edges, whether the incident vertices
of each edge are active when the edge is active
$vertex.tea.checks : Corresponding to vertices, whether the vertex has
correctly formed TEA attributes
$edge.tea.checks : Corresponding to edges, whether the edge has
correctly formed TEA attributes
$network.tea.checks : Single boolean, whether the network TEA attributes are formed correctly
$net.obs.period.check : NULL, if no net.obs.period network attribute is present, otherwise a single boolean, whether the attribute is formed correctly.
For is.networkDynamic: a boolean which is true if the class matches
