In arunsrinivasan/flights: Data about On-Time Performance of flights in the US

flights

flights contains functions to download and load flights data from the Bureau of Transportation Statistics. It also contains functions to generate On-time data for flights that departed from NYC (i.e. JFK, LGA or EWR) in 2014. Specifically, nycflights14, nycdelays14 and nycweatherdelays14.

Installation

To install the package, use devtools:

devtools::install_github("arunsrinivasan/flights")

Usage

Download flight logs

downloadflightlogs (year = 2014L, month = 1:12, path = "./", dir = "flights", 
    verbose = TRUE)

The function takes a year and month argument and downloads all the logs available from here and places them in the directory path/dir. The downloaded files are automatically replaced with their unzipped versions. If an unzipped log file already exists, then the downloads are skipped. And if the downloaded file was corrupted (which would error while unzipping), then we attempt to download it just once again. If it fails again, we skip this log.

Load entire flights data

flights (year = 2014L, month = 1:12, path = "./", dir = "flights", 
    select = NULL, verbose = TRUE) 

This loads all the 100+ columns for the downloaded logs. Note that at the time of writing, logs for 2014 are available until the month of October.

nycflights14

nycflights14 (path = "./", dir = "flights", verbose = TRUE)

Loads columns identical to flights data from nycflights13, except for the year 2014.

nycdelays14

nycflights14 (path = "./", dir = "flights", verbose = TRUE)

Loads columns providing additional information about the type of delays for all flights that departed from NYC in 2014.

nycweatherdelays14

nycweatherflights14 (path = "./", dir = "flights", verbose = TRUE)

Same as above, but returns only those rows where weather_delay > 0L.
