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

Install the stable version of this package from CRAN or the ffverse r-universe repository:

install.packages("ffscrapr") # CRAN
install.packages("ffscrapr", repos = "https://ffverse.r-universe.dev")

Install the development version from GitHub with:

remotes::install_github("ffverse/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)

# Get a summary of league settings
ff_league(ssb) %>% str()

# Get rosters
ff_rosters(ssb)

# Get transactions
ff_transactions(ssb)
