Create a language network from a list of items. This version segments items based on a specified separator when specifying neighbors.

make_network_sep.Rd

Create a language network from a list of items. This version segments items based on a specified separator when specifying neighbors.

Usage

make_network_sep(
  item_df,
  separator = ".",
  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".

separator

A single character. The default is '.'. This is used to segment items into sub-units to base the neighborhood computation on.

neighbor_type

A string indicating neighbor type: "lv" (default) is 1-edit neighbors by substitution, deletion, or addition; "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.
