aopdata v1.2.0

Major changes

• Data files are now downloaded with {httr2}. If a file can’t be downloaded from the Ipea server, that file is downloaded from the GitHub mirror, so a single unavailable file or server no longer makes the whole request fail. When several files are downloaded at once, the progress bar counts files; when only one file is downloaded, it shows the amount of data downloaded.
• aopdata now requires R >= 4.1.0 (a requirement of {httr2}).

Bug fixes

• HTTP errors (e.g. 404 pages) are no longer saved and read as data.
• Interrupted or corrupted downloads are no longer reused from the session cache: files are saved only once they are complete, and a cached file that can’t be read is removed.
• Downloads that stall are now stopped instead of hanging the R session.
• The metadata file is now downloaded with the same downloader as the data files (GitHub release first, Ipea server as fallback), and cached only once it has been read successfully. A broken cached metadata file is downloaded again instead of making every later call in the session fail.
• Grids (geometry = TRUE or read_grid()) of several cities now have a bounding box that covers all the cities, and are a plain sf data frame. Previously the bounding box covered only the first city, so maps of several cities could be cropped.
• When a download fails, the user now sees one message that says what failed. Previously the functions could print “No internet connection.” up to three times, even when only one file was unavailable.

Minor changes

• Documentation corrected to match the data: the years and cities of each transport mode, the off-peak window, time thresholds, the TMI indicators, the defaults of read_population(year) and read_grid(showProgress), and return types.
• Typos fixed in the documentation and vignettes; the package citation (citation("aopdata")) now lists the two Ipea discussion papers as technical reports, with their DOIs.
• City codes and names can now be mixed, in any capitalisation and with or without accents, in every function (e.g. city = c('nat', 'São Paulo')). Previously a mix returned NULL or a misleading error, and only read_access() accepted upper-case city codes and 'ALL'.
• Invalid inputs now give a clear error before any data is downloaded: city missing, NULL, NA or not text; an unknown city (the error names it and lists the valid codes and names); and a mode that a requested city doesn’t have (the error names the city and lists the cities with that mode).
• peak, geometry and showProgress must be a single TRUE or FALSE. showProgress = 1/0 is no longer accepted, and NA or vectors give an error instead of a base R error. A vector year also gives a clear error; one year per call is supported.
• Which cities have public transport is now taken from the metadata instead of lists hard-coded in read_access().
• aopdata_dictionary() now only accepts lang = "en" or "pt"; values such as "english" were accepted before and silently did nothing.
• All messages and errors now use {cli}. Errors have the condition class aopdata_error, and messages about failed downloads have the class aopdata_network, so they can be caught with tryCatch() or withCallingHandlers(). Download failure messages are now rlang_messages (previously cliMessage). The wording of the errors for invalid arguments, mode and showProgress changed, so match on the condition class rather than on the message text.
• The “Downloading … data” messages are now only shown when showProgress = TRUE. The “Using mode” message was removed.

aopdata v1.1.2

Minor changes

• Messages and errors now use {cli}
• Avoid printing internet connection messages twice

Bug fixes

• Updated vignettes to avoid error in case of eventual internet connection issue.
• Now using the latest version of {rmarkdown}.

aopdata v1.1.1

Bug fixes

• Download functions should now fail gracefully with an informative message when there are internet connection problems. Making sure to propagate the internet connection issue across function levels.

aopdata v1.1.0

Minor changes

• Simplified internal functions
• Removed dependency on the {httr} package
• Now using curl::multi_download() to download files in parallel

aopdata v1.0.3

Bug fixes

• Simplified internal functions
• Download functions should now fail gracefully with an informative message when there are internet connection problems. Using a more robust solution now that also accounts for timeout.

aopdata v1.0.2

Bug fixes

• Fixed bug that printed message ‘connection fail’ in the 1st attempt, when it should only print in the 2nd attempt
• updated CITATION file with bibentry()

aopdata v1.0.1

Minor changes

• Remove code redundancy from main read_ and download function
• Do not throw connection error message in first check
• Improve error message when mode = car. Closes #52
• Added citation file

Bug fixes

• Fixed bug that did not allow one to download access estimates by car in off-peak period. Closes #53

aopdata v1.0.0

Major changes

• New function aopdata_dictionary() to open the aopdata data dictionary on a web browser.
• All data sets are now simultaneously stored on github and on Ipea’s server. The package now downloads the data from github. In case the github link is off line for some reason, then the package tries to download the data from Ipea’s server. For users, the effect of this change is that the package is much more stable and less vulnerable to instabilities in Ipea’s data server connection.
• New data sets:
  • Year coverage
    • Access and Land use data sets now cover years 2017, 2018 and 2019
  • New cities
    • Data for Goiania now covers the entire metro area of Goiania in 2019.
  • New modes
    • Access data now bring accessibility estimates by car in 2019
  • New activities
    • Land use and access data now bring data for centers for social assistance (CRAS)
    • Population data sets with minor spatial corrections to smooth spatial distributions

Minor changes

• read_ functions now have no default value for the city parameter. Closes #38.
• Fixed ERROR message when there is no data for a particular transport mode for a specific city & year.

aopdata v0.2.3

Minor changes

• Download functions should now fail gracefully with an informative message when there are internet connection problems.
• Remove crul from package dependencies.
• skip examples on CRAN. Examples now only run on interactive R sessions.
• update links from http to https

aopdata v0.2.2

Minor changes

• Adds crul as a package dependency. Now aopdata fails gracefully when there is internet connection problems. Closes #32.
• showProgress now sets to FALSE in all tests, examples and vignettes. Closes #32.
• skip tests on CRAN. Tests are run only locally

aopdata v0.2.1

Minor changes

• Allow for user to download data few selected cities. Closes #29
• Fix progress bar even when showProgress = F. Closes #30
