cv <- trainControl(
  method = "cv",
  number = 5,
  classProbs = TRUE,
  summaryFunction = prSummary,
  seeds = set.seed(123))

turn_grid_xgb <- expand.grid(
  eta = c(0.1,0.3,0.5),
  max_depth = 5,
  min_child_weight = 1,
  subsample = 0.8,
  colsample_bytree = 0.8,
  nrounds = (1:10)*200,
  gamma = 0)

set.seed(123)
suppressWarnings({
  xgb_1 <- train(label~., data = baked_train, 
             method = "xgbTree",
             tuneGrid = turn_grid_xgb,
             trControl = cv,
             verbose = FALSE,
             metric = "F")

您好，当我尝试运行上面的代码时，R 控制台中显示以下警告。有谁知道如何摆脱它？我已经尝试过suppressWarnings()，warning = FALSE在块设置上，它仍然存在。

谢谢！！
