The functions listed here are deprecated. This means that they once existed in earlier versions of the of the prioritizr package, but they have since been removed entirely, replaced by other functions, or renamed as other functions in newer versions. To help make it easier to transition to new versions of the prioritizr package, we have listed alternatives for deprecated the functions (where applicable). If a function is described as being renamed, then this means that only the name of the function has changed (i.e., the inputs, outputs, and underlying code remain the same).

The following functions have been deprecated:

`add_connected_constraints()`

renamed as the

`add_contiguity_constraints()`

function.`add_corridor_constraints()`

replaced by the

`add_feature_contiguity_constraints()`

function.`set_number_of_threads()`

no longer needed used with the implementation of superior data extraction.

`get_number_of_threads()`

no longer needed used with the implementation of superior data extraction.

`is.parallel()`

no longer needed used with the implementation of superior data extraction.

`add_pool_portfolio()`

replaced by the

`add_extra_portfolio()`

and`add_top_portfolio()`

.`connected_matrix()`

renamed as the

`adjacency_matrix()`

function.`feature_representation()`

replaced by the

`eval_feature_representation_summary()`

function for consistency with other functions.`replacement_cost()`

renamed as the

`eval_replacement_importance()`

function for consistency with other functions for evaluating solutions.`rarity_weighted_richness()`

renamed as the

`eval_rare_richness_importance()`

function for consistency with other functions for evaluating solutions.`ferrier_score()`

renamed as the

`eval_ferrier_importance()`

function for consistency with other functions for evaluating solutions.
