In bikedata: Download and Aggregate Data from Public Hire Bicycle Systems

0.2.3

Minor changes: - Fix dl_bikedata for Philadelphia - Improve robustness of tests

0.2.2

Minor changes: - add NEWS & README to CRAN description - Minor bug fixes

0.2.1

• New helper function bike_cities to directly list cities included in current package version

Minor changes: - Bug fix for San Fran thanks to @tbdv (see issue #78) - Bug fix for LA (see issue #87)

0.2.0

• Major expansion to include new cities of San Francisco, Minneapolis/St Paul, Montreal Canada, and Guadalajara Mexico
• Most code restructured to greatly ease the process of adding new cities (see github wiki for how to do this).
• New co-author: Tom Buckley

Minor changes: - Bug fix for LA data which previously caused error due to invisible mac OSX system files being bundled with the distributed data - More accurate date processing for quarterly LA data

0.1.1

• Important bug in dodgr package rectified previously bug-ridden bike_distmat() calculations (thanks Joris Klingen).
• Files for Washington DC Capital Bike Share system changed from quarterly to annual dumps
• One rogue .xlsx file from London now processed and read properly (among all other well-behaved .csv files).
• Update bundled sqlite3: 3.21 -> 3.22

0.1.0

• New function bike_distmat() calculates distance matrices between all pairs of stations as routed through street networks for each city.
• Helper function bike_match_matrices() matches distance and trip matrices by start and end stations, so they can be directly compared in standard statistical routines.
• North American Bike Share Association (NABSA) systems (currently LA and Philly) now distinguish member versus non-member based on whether usage is 30-day pass or "Walk-up".

minor changes - dl_bikedata() function also aliased to download_bikedata(), so both do the same job. - Repeated runs of store_bikedata() on pre-existing databases sometimes re-added old data. This has now been fixed so only new data are added with each repeated call. - Dates for NABSA cities (LA and Philadelphia) are given in different formats, all of which are now appropriately handled. - Internally bundled sqlite3 upgraded v3.19 -> v3.21

0.0.4

• Database no longer automatically indexed; rather indexes must be actively generated with index_bikedata_db(). This makes multiple usages of store_bikedata() faster and easier.
• store_bikedata() fixed so it only unzips files not already in database (it used to unzip them all)
• Internal changes to improve consistency (mostly through using the DBI package).

0.0.3

• Minor changes only
• More informative messages when data for specified dates not available

0.0.2

• No change to package functionality
• Drop dplyr dependency after dplyr 0.7 upgrade

0.0.1 (31 May 2017)

• Initial CRAN release
