The {ffsimulator}
package uses bootstrap resampling to run fantasy
football season simulations supported by historical rankings and
nflfastR data, calculating optimal lineups, and returning aggregated
results. This can quickly run your league through hundreds of seasons
and builds out the data to help you study:
This package is part of the ffverse family of R packages for fantasy football analysis.
Install the stable version of this package from CRAN:
install.packages("ffsimulator") # CRAN
Install the development version from either r-universe or GitHub:
install.packages("ffsimulator", repos = "https://ffverse.r-universe.dev")
# pak is recommended, see https://github.com/r-lib/pak
pak::pak("ffverse/ffsimulator")
# can also use remotes
remotes::install_github("ffverse/ffsimulator")
The development version has a separate documentation site here.
A season simulation can be run as follows:
library(ffsimulator)
library(ggplot2)
library(ggridges)
mfl_conn <- mfl_connect(season = 2021, league_id = 22627)
## OTHER PLATFORM CONNECTIONS MAY BE USED, FOR EXAMPLE:
# sleeper_conn <- sleeper_connect(season = 2021, league_id = "652582284720971776")
# flea_conn <- fleaflicker_connect(season = 2021, league_id = 312861)
# espn_conn <- espn_connect(season = 2021, league_id = 899513)
mfl_sim <- ff_simulate(conn = mfl_conn, n_seasons = 100)
plot(mfl_sim)
