ffscrapr

An R Client for Fantasy Football League APIs

CRAN status Dev status Lifecycle: stable Codecov test coverage R build status API status nflverse discord

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:

install.packages("ffscrapr")

Install the development version from either r-universe or GitHub:

install.packages("ffscrapr", repos = "https://ffverse.r-universe.dev")
# pak is recommended, see https://github.com/r-lib/pak
pak::pak("ffverse/ffscrapr")
# can also use remotes
remotes::install_github("ffverse/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 17] (S3: tbl_df/tbl/data.frame)
#>  $ league_id        : chr "54040"
