fio 0.1.0

✨ Enhancements

• New import_element() to programmatically import data from an Excel file
• New data import addin makes easy to import data from clipboard or an Excel file
• New iom uses the efficiency of R6 classes
• New add and remove methods to add and remove elements from an iom object
• New br_2020 dataset with a 51 sector Brazilian input-output table for 2020
• New compute_tech_coeff() and compute_leontief_inverse() methods uses the power of Rust and faer crate to substantially increase performance
• New compute_multiplier_*() methods to compute multipliers from a given input-output table:
  • compute_multiplier_output() for the output multiplier
  • compute_multiplier_employment() for the employment multiplier
  • compute_multiplier_wages() for the wages multiplier
  • compute_multiplier_taxes() for the taxes multiplier
• New compute_influence_field() method to compute the field of influence of each sector
• New compute_key_sectors() method to compute the key sectors of an input-output table, based on power of dispersion and sensitivity of dispersion, and their coefficients of variations
• New compute_allocation_coeff() method to compute the allocation coefficients of an input-output table
• New compute_ghosh_inverse() method to compute the Ghosh inverse of an input-output table
• New compute_hypothetical_extraction() method to compute impact on demand, supply and both structures after hypothetical extraction of a sector
• New set_max_threads() method to allow the user to control number of threads used by {fio} (required by CRAN).

🚀 Performance improvements

• Use Rust instead of base R for compute_*() functions
• Use faer crate instead of nalgebra for faster linear algebra calculations
• Use R6 classes for a clean, object state-changes, memory-efficient object-oriented programming

🛠️ Other improvements

• Added assertions to check if elements imported into slots are matrices at initialization of iom object and at add() method
• Added assertions to check matrices dimensions at initialization of iom object and at add() method
• More informative warnings and errors messages with {cli} package
• Added assertions to check if number format of slots is double at initialization of iom object and at add() method
