save_raw_pbp: Download Raw PBP Data to Local Filesystem

In nflfastR: Functions to Efficiently Access NFL Play by Play Data

Download Raw PBP Data to Local Filesystem

Description

The functions build_nflfastR_pbp() and fast_scraper() support loading raw pbp data from local file systems instead of Github servers. This function is intended to help setting this up. It loads raw pbp data and saves it in the given directory split by season in subdirectories.

Usage

save_raw_pbp(
  game_ids,
  dir = getOption("nflfastR.raw_directory", default = NULL)
)

Arguments

game_ids	A vector of nflverse game IDs.
dir	Path to local directory (defaults to option "nflfastR.raw_directory"). nflfastR will download the raw game files split by season into one sub directory per season.

Value

The function returns a data frame with one row for each downloaded file and the following columns:

• success if the HTTP request was successfully performed, regardless of the response status code. This is FALSE in case of a network error, or in case you tried to resume from a server that did not support this. A value of NA means the download was interrupted while in progress.

• status_code the HTTP status code from the request. A successful download is usually 200 for full requests or 206 for resumed requests. Anything else could indicate that the downloaded file contains an error page instead of the requested content.

• resumefrom the file size before the request, in case a download was resumed.

• url final url (after redirects) of the request.

• destfile downloaded file on disk.

• error if success == FALSE this column contains an error message.

• type the Content-Type response header value.

• modified the Last-Modified response header value.

• time total elapsed download time for this file in seconds.

• headers vector with http response headers for the request.
