ffscrapr

An R Client for Fantasy Football League APIs

CRAN status Lifecycle: maturing Codecov test coverage R build status

Helps access various Fantasy Football APIs (i.e. MFL, Sleeper, Fleaflicker, ESPN, Yahoo, potentially other platforms) by handling authentication and rate-limiting, forming appropriate calls, and returning tidy dataframes which can be easily connected to other data sources.

Installation

Install from GitHub with:

# install.packages("devtools") OR install.packages("remotes")
## remotes is a subpackage of devtools
remotes::install_github("dynastyprocess/ffscrapr")

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()
