错误：不是公认的重采样方法

Question

我无法运行我的模型来平衡我的数据框。它告诉我你不认识重采样方法。我该怎么办？

> # Criando funcao controle para o treino
> ctrl <- trainControl(method = "repeateadcv",
+                      number = 10,
+                      repeats = 5,
+                      summaryFunction = twoClassSummary,
+                      classProbs = TRUE)
Warning message:
`repeats` has no meaning for this resampling method.

Error: Not a recognized resampling method.

Answer 1

问题在于超参数方法。是“repeatedcv”，不是“repeateadcv”，没有a。
