In flightsbr: Download Flight and Airport Data from Brazil

flightsbr v1.1.0

Major changes:
The default of all read_ functions now is to download data from the latest date available.
The function read_aircrafts() is now deprecated in favor of read_aircraft() simply to fix a typo in the function name. The behavior and outputs are identical. Closes #45
CRAN policy:
updaed DESCRIPTION file removing 'NeedsCompilation'

flightsbr v1.0.0

Breaking changes:
The names of all columns in the data outputs are now cleanned with {janitor}
Function read_airports() now downloads v2 version of public airports data. Closes #41
Major changes:
Function read_airfares() is working again. Closes #30. The prices of air tickets are now returned as numeric.
Function read_flights() with fixed decimal values in numeric columns. Closes #43
Function read_airports() with fixed numeric values for "altitude" column. Closes #42
Minor changes:
Internally check of the consistency of date inputs. The date input must be consistent in either a 6-digit format yyyymm OR a 4-digit format yyyy.
New support function latest_airfares_date()
Fix error that stopped reading aircraft data read_aircraft() for multiple months when the number of collums differed across months. Fixed using data.table::rbindlist(fill = TRUE)

flightsbr v0.5.0

Major changes:
Fixed ANAC's broken link of public airports
Functions read_flights(), read_airport_movements(), and read_aircraft() now accept vectors of dates like c(202201, 202301) or c(2022, 2024)
Functions read_airports() and read_aircraft() now has a cache parameter.
The package is now significantly faster because it is using curl::multi_download() to download files in parallel. This brings the advantage that the package now automatically detects whether the data file has been updated and should be downloaded again.
Minor changes:
Removed dependency on the {httr} package
Streamlined functions to simplify package maintenance and improve performance
Using {fs} to manage file paths and {archive} to unzip files
Reorganization of internal functions to simplify package maintenance

flightsbr v0.4.1

The read_flights() function now uses fread(encoding = 'Latin-1') internally to avoid issues with encoding. Closed #35.
The function get_airport_movement_dates_available() does not throw warnings of NA values anymore.
The read_aircraft() function now used fread(skip = 1) internally to read column names correctly.

flightsbr v0.4.0

Major changes:
The functions read_flights() and read_airport_movements() now have a new parameter cache, which indicates whether the function should read cached data downloaded previously. Defaults to TRUE. Closed #31.
The function read_aircraft() now has a date parameter, which allows one to download the data on aircraft registered at ANAC at particular years/months. Closed #33.
Minor changes:
All functions now return numeric columns with numeric class. Closed #32.
Bug fixes:
Fixed bug when unzipping files for read_flights() function in Unix systems. Closed #31.

Fixed code to rbindlist air fares from multiple years. Closed #26.
Fixed code to read a few dates that were not caught in get_airfares_dates_available() because of ".CSV" in ANAC url. Closed #27.
Fixed code to use get_airport_movement_dates_available()

Bug fixes:
Fixed bug in read_flights() due to changes in ANAC data links.
Fixed broken link in intro_flightsbr vignette

Fixed bug that stopped flightsbr from downloading 2022 data.

read_ functions now try to download for a 2nd time if the 1st attempt failed. This will help overcome a small issue with the instability of ANAC data links. Closed #18.
Using a simpler / slightly faster version of latlon_to_numeric() with suppressed warnings.
Update package citation, adding OSF preprint DOI.

flightsbr v0.1.0

Major changes:
New function read_aircraft() to read data on all aircraft registered in the Brazilian Aeronautical Registry (Registro Aeronáutico Brasileiro - RAB) Closed #14.
