In jrnold/groundcontrol: Create a Custom Dataset of On-time Flights

Description Usage Arguments Details Value Examples

Create a data-only R pacakge of flights data, like nycflights13, but with user-specified airports, years, and direction (departing, arriving).

download_flightdata(airport_codes, year, data_dir = "./data",
  raw_dir = "./data-raw", origin = TRUE, dest = FALSE,
  all_weather = FALSE)

create_flights(path, airport_codes, year, origin = TRUE, dest = FALSE,
  all_weather = FALSE, description = getOption("devtools.desc"))

`airport_codes`	A character vector of airport codes
`year`	Year of flights to download.
`data_dir`	Directory to save `.rda` file.
`raw_dir`	Directory to save `.csv` and intermediate files.
`origin, dest`	If `origin` (`dest`) is `TRUE`, keep all flights originating from (arriving at) `airports`. At least one of `origin` or `dest` must be `TRUE`.
`all_weather`	If `TRUE`, get weather for not just the chosen airports, but also all (domestic) airports appearing in the flight data.
`path`	Location to create new package. The last component of the path will be used as the package name.
`description`	A `list` of description values to override default values or add additional values.

The function create_flights creates an R package with the flight data. The function download_flightdata downloads the data and saves .csv and .rda files to specified directories, but does not create an R package.

A "package" object for the created package. This function is called for the side-effect of downloading the data and creating a package.
