The backbone of the ffsimulator resampling process is coming up with a population of weekly outcomes for every preseason positional rank. This function creates that dataframe by connecting historical FantasyPros.com rankings to nflfastR-based scoring data, as created by ffscrapr::ff_scoringhistory().
Usage
ffs_adp_outcomes(
scoring_history,
gp_model = "simple",
pos_filter = c("QB", "RB", "WR", "TE")
)Arguments
- scoring_history
a scoring history table as created by
ffscrapr::ff_scoringhistory()- gp_model
either "simple" or "none" - simple uses the average games played per season for each position/adp combination, none assumes every game is played.
- pos_filter
a character vector: filter the positions returned to these specific positions, default: c("QB","RB","WR","TE)
Value
a dataframe with position, rank, probability of games played, and a corresponding nested list per row of all week score outcomes.
