Update static node attributes

Usage

update_nodes(dn, data)

Arguments

dn: A temporal network.
data: A nonempty data frame with a name key and one or more attributes to add or replace. Only named nodes are changed.

Value

A new dynet object, class c("dynet", "netobject", "cograph_network"), with the same spells, vertex activity and metadata as dn and the supplied attributes added to or replaced on the named vertices. Unnamed vertices keep their existing values, gaining NA in any column the network did not already have. Raises dynet_unknown_node when a name is not a vertex, and dynet_bad_input when data is malformed or names a cograph structural column (id, label, x, y).

Examples

dn <- dynet(data.frame(from = "A", to = "B", start = 0, end = 1))
update_nodes(dn, data.frame(name = "A", role = "initiator"))
