我正在使用tidymodels进行机器学习，我想预测二元响应/结果。如何指定哪个级别的结果是“事件”或积极案例？

这种情况发生在食谱中还是其他地方？

##split the data
anxiety_split <- initial_split(anxiety_df, strata = anxiety)


anxiety_train <- training(anxiety_split)
anxiety_test <- testing(anxiety_split)


set.seed(1222) 
anxiety_cv <- vfold_cv(anxiety_train, strata = anxiety)

anxiety_rec <- recipe(anxiety ~ ., data = anxiety_train, positive = 'pos') %>%
  step_corr(all_numeric()) %>%
  step_dummy(all_nominal(), -all_outcomes()) %>%
  step_zv(all_numeric()) %>%
  step_normalize(all_numeric())
