In langfob/bdpg: Package For Building and Testing Biodiversity Problem Generators

Create adjacency matrix with species rows vs planning unit columns

Description

Create numeric adjacency matrix with one row for each species and one column for each planning unit and each matrix entry specifying whether that species occupies that planning unit. A 1 indicates the species does occupy the planning unit and 0 indicates it does not.

Usage

create_adj_matrix_with_spp_rows_vs_PU_cols(
  num_spp,
  num_PUs,
  PU_spp_pair_indices,
  PU_costs,
  spp_col_name,
  PU_col_name,
  dependent_node_IDs,
  correct_solution_vector_is_known
)

Arguments

num_spp	integer number of species in the problem
num_PUs	integer number of planning units
PU_spp_pair_indices	2 column data frame of PU IDs vs species IDs, where each row identifies a the ID of a given species that occurs on the given planning unit
PU_costs	numeric vector of planning unit costs
spp_col_name	character string giving species column name in data frames
PU_col_name	character string giving planning unit column name in data frames
dependent_node_IDs	integer vector of IDs of planning units contained in a constructed correct solution to a Xu problem
correct_solution_vector_is_known	boolean flag indicating whether a correct optimal solution vector is known for the problem (as opposed for example, to only knowing the correct cost)

Value

Returns bpm; integer matrix with one row for each species and one column for each planning unit. Each matrix entry specifies whether that species occupies that planning unit; 1 indicates the species does occupy the planning unit and 0 indicates it does not.
