The fflr package is used to query the ESPN Fantasy Football API. Get data on fantasy football league members, teams, and individual athletes.

This package has been tested with a narrow subset of possible league settings. If a function doesn’t work as intended, please file an issue on GitHub.

Installation

You can install the release version of fflr from CRAN:

install.packages("fflr")

The most recent development version can be installed from GitHub:

# install.packages("remotes")
remotes::install_github("kiernann/fflr")

Usage

library(fflr)
packageVersion("fflr")
#> [1] '2.2.0'

Data is only available for public leagues. See this help page on how to make a private league public

Functions require a unique leagueId, which can be found in any ESPN page URL.

https://fantasy.espn.com/football/league?leagueId=42654852

Use ffl_id() to set a default fflr.leagueId option. Your .Rprofile file can set this option on startup.

ffl_id(leagueId = "42654852")
#> Temporarily set `fflr.leagueId` option to 42654852
#> [1] "42654852"

The leagueId argument defaults to ffl_id() and can be omitted once set.
