An R Client for Fantasy Football League APIs

Helps access various Fantasy Football APIs (currently MFL, Sleeper, Fleaflicker, and eventually ESPN, 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 1.2.1 is now on CRAN 🎉 and can be installed with:

install.packages("ffscrapr")
# or from GitHub release with the remotes package # install.packages("remotes")
remotes::install_github("dynastyprocess/ffscrapr",ref = "v1.2.1")

Install the development version from GitHub with:

remotes::install_github("dynastyprocess/ffscrapr")

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()
#> tibble [1 x 13] (S3: tbl_df/tbl/data.frame)
#>  $ league_id      : chr "54040"
