Create a language network from a list of items. This version takes each single character as an individual segment when specifying neighbors.

Usage

make_network(
  item_df,
  neighbor_type = "lv",
  network_name = "test",
  edit_size = 1
)

Arguments

item_df: A data frame containing the list of items and other node-level attributes that are appended to the network (optional). Must minimally contain one character class column labeled "item".
neighbor_type: A string indicating neighbor type: "lv" (default) is 1-edit neighbors by substitution, deletion, or addition; "osa" is 1-edit neighbors by substitution, deletion, addition, or transposition; "hamming" is 1-edit neighbors by substitution only.
network_name: A string, the name of the network. Becomes a network-level attribute.
edit_size: An integer that indicates the maximum edit distance allowed between word pairs that are connected in the network. Default value is 1.

Value

An igraph network object.
