Question

我正在尝试使用以下设置来调整一些模型以为实验做准备：


export const Types = {
  PAUSE: 'player/PAUSE',
};

const initialState = {
  status: 'PLAYING',
};

export default function reducer(state = initialState, action) {
  switch (action.type) {
    case Types.PAUSE:
      return { ...state, status: 'PAUSE' };
    default:
      return state;
  }
}

// Action Creators
export function pause() {
  return dispatch => {
    dispatch({
       type: Types.PAUSE
    });
  };
}

我加载了必要的库和默认数据集：

运行这段代码时，出现以下错误和警告：

# load libraries
library(mlbench)
library(caret)
library(doMC)
registerDoMC(cores=8)

# load data
data(PimaIndiansDiabetes)
dataset <- PimaIndiansDiabetes
x <- dataset[,1:8]
y <- dataset[,9]

# prepare simple test suite
control <- trainControl(method="cv", number=5)
seed <- 7
metric <- "Accuracy"

# Ordered Logistic or Probit Regression
set.seed(seed)
fit.polr <- train(diabetes~., data=dataset, method="polr", metric=metric, preProc=c("center", "scale"), trControl=control)

我不确定如何更正这些错误。
