Operations on `preferences`

preferences are a bit like character vectors in that a single element comprises a string of information. To operate on many preferences at once, a variety of tools are provided which facilitate basic operations.

pref_get_items(): Get the name of the item(s) assigned a specific rank, e.g., first.

pref_get_rank(): Get the rank assigned to a specific item in a set of preferences.

pref_keep(): Keep only specified items from preferences.

pref_length(): Check the length (number of rankings) of a preference.

pref_omit(): Remove specified items from preferences.

pref_pop(): Eliminate lowest (or highest) ranked items from preferences.

pref_rev(): Reverse preference rankings

pref_trunc(): Truncate preferences to a maximum number of ranks.

Summaries of `preferences`

Compute summaries on preferences, e.g., covariance matrices, rankings matrix, adjacency matrix and even compute an instant-runoff voting outcome.

pref_cov(): Covariance matrix for preferences, calculated using the rankings matrix.

pref_irv(): Compute the instant-runoff voting winner for a set of preferences.

pref_type(): pref_type

ranking_matrix(): Compute the Rankings Matrix for a vector of preferences

adjacency(): Compute the Adjacency Matrix for a vector of preferences
