An R Client for Fantasy Football League APIs
Helps access various Fantasy Football APIs (currently MFL, Sleeper, Fleaflicker, and ESPN - eventually Yahoo, potentially others) by handling authentication/rate-limiting/caching, forming appropriate calls, and returning tidy dataframes which can be easily connected to other data sources.
Installation
Version 1.4.3 is now on CRAN 🎉 and can be installed with:
install.packages("ffscrapr")
# or from GitHub release with the remotes package via:
# install.packages("remotes")
remotes::install_github("dynastyprocess/ffscrapr", ref = "v1.4.3")Install the development version from GitHub with:
remotes::install_github("dynastyprocess/ffscrapr", ref = "dev")The dev version has a separate documentation site here.
Usage
All ffscrapr functions start with a connection object created by ff_connect(), which stores connection, authentication, and other user-defined parameters. This object is used by all other functions to help return the correct data.
library(ffscrapr)
ssb <- ff_connect(platform = "mfl", league_id = "54040", season = 2020)
