Arguments

x	Network input.
labels	Character vector of labels for the new nodes.
...	Named vectors of node attributes for the new nodes, each of length 1 (recycled) or length(labels). Columns the network does not already have are created and filled with NA for the existing nodes.
keep_format	Logical. Return the input format when TRUE.
directed	Logical or NULL. If NULL (default), auto-detect.

Value

A cograph_network with the new nodes appended (isolated until edges are added), or the input format when keep_format = TRUE.
