An R Client for Fantasy Football League APIs
Helps access various Fantasy Football APIs (currently MFL, Sleeper, Fleaflicker, and ESPN - perhaps eventually Yahoo and others) by handling authentication/rate-limiting/caching, forming appropriate calls, and returning tidy dataframes which can be easily connected to other data sources.
Install the stable version of this package from CRAN:
Install the development version from either r-universe or GitHub:
install.packages("ffscrapr", repos = c("https://ffverse.r-universe.dev", getOption("repos"))) # pak is recommended, see https://github.com/r-lib/pak pak::pak("ffverse/ffscrapr") # can also use remotes remotes::install_github("ffverse/ffscrapr")
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.
