This function performs pre-processing steps to make
expected points predictions on nflreadr data
Arguments
- pbp
pbp dataframe from
nflreadr::load_pbp()
Value
a list of two dataframes (one for passes and one for rushes) of nflreadr data with the expectedpoints columns transformed for prediction
Examples
# \donttest{
try({ # catch failures for CRAN purposes
pbp_download <- readRDS(system.file("pbp_download.rds",package = "ffopportunity"))
# this file is equivalent to nflreadr::load_pbp(2021) %>% head(1000)
ep_preprocess(pbp_download)
})
