as_dynet.networkDynamic: Import a networkDynamic object

In Dynet: Tidy Temporal Network Analysis

Import a networkDynamic object

Description

Converts the edge-activity spell ledger, observation support, explicit vertex activity, weights, static vertex attributes, and static edge attributes of a networkDynamic object. Integer vertex identifiers are replaced by a complete unique vertex attribute. By default Dynet tries Name, Label, and then vertex.names, in that order.

Usage

## S3 method for class 'networkDynamic'
as_dynet(
  x,
  name_attribute = NULL,
  group_attribute = NULL,
  weight_attribute = "weight",
  session_attribute = NULL,
  interval = NULL,
  active_default = TRUE,
  import_edge_attributes = TRUE,
  ...
)

Arguments

x	A networkDynamic object.
name_attribute	Optional vertex attribute holding the public node names. NULL chooses the first complete unique attribute among Name, Label, and vertex.names.
group_attribute	Optional static vertex attribute used as the cograph grouping variable.
weight_attribute	Static edge attribute used as spell weight, "weight" by default. Supply NULL to use unit weights. A name that is not a static edge attribute of x also yields unit weights.
session_attribute	Optional static edge attribute used as the spell session label. NULL, the default, leaves the network unsessioned; a name that is not a static edge attribute raises a condition of class dynet_unknown_attribute.
interval	Positive measurement interval. NULL, the default, uses the legacy observation time increment when available, otherwise one.
active_default	Whether legacy edges with no explicit activity spell are active over the observation period, matching the same argument in networkDynamic. TRUE by default.
import_edge_attributes	Whether to retain compatible static legacy edge attributes on the raw Dynet spell ledger. TRUE by default; an attribute whose name would collide with a canonical spell column is prefixed with edge_.
...	Ignored.

Details

Dynamic edge attributes other than activity itself are not part of the networkDynamic spell-list interface and are therefore not imported. Ordinary per-edge attributes are repeated onto every imported spell of the corresponding aggregate edge, matched on the canonical endpoint order dynet() stores, so an undirected pair carries its own attributes.

Value

A dynet() temporal network: an object of class c("dynet", "netobject", "cograph_network") whose spell table has one row per imported edge-activity spell, with the legacy vertex and edge attributes, observation support, vertex activity and censor flags carried across. Its metadata additionally carries legacy_source = "networkDynamic", the chosen legacy_name_attribute, the retained legacy_edge_attributes and any legacy_edge_attribute_renames.

Examples

if (requireNamespace("networkDynamic", quietly = TRUE) &&
    requireNamespace("network", quietly = TRUE)) {
  spells <- data.frame(onset = c(0, 1), terminus = c(2, 3),
                       tail = c(1, 2), head = c(2, 3))
  legacy <- networkDynamic::networkDynamic(edge.spells = spells)
  network::set.vertex.attribute(legacy, "Name", c("A", "B", "C"))
  dn <- as_dynet(legacy)
  as.data.frame(dn)
}
