Question

使用rpart()进行分类树分析时，我能够手动计算准确性。但是，我不确定如何计算其余的分类指标，即精度和召回率。

这就是我决定继续进行的方式，在这篇文章的结尾，我将dput()训练和测试数据集用于可复制性：

#Model implementation

> head(tableresults)
  ACTIVITY_X ACTIVITY_Y classification
1         40         47 Moving/Feeding
2         60         74       Standing
3         62         63       Standing
4         60         56       Standing
5         66         61       Standing
6         60         53       Standing

# Generating test and train data with a 80/20 split

trainIndex  <- sample(1:nrow(tableresults), 0.8 * nrow(tableresults))
train <- tableresults[trainIndex,]
test <- tableresults[-trainIndex,]

# Tree construction based on information gain
xtree <- rpart(classification ~ ACTIVITY_X + ACTIVITY_Y , data = train, method = "class", parms = list(split = "information"))

现在，我打算使用tableresults作为预测变量，根据resp41366和ACTIVITY_X的值来预测ACTIVITY_Y数据集的标签。 resp41366的标签是已知的，以后将用于计算准确性：

#Running the model

> resp41366_pred413561 = predict(xtree,resp41366,type="class")
> resp41366_pred413561<-data.table(resp41366_pred413561)
> names(resp41366_pred413561)="predicted"

#Merging the observed classes with the predicted classes by the model

> test_accuracy<-cbind(resp41366_observed,resp41366_pred413561)
> head(test_accuracy)
         observed      predicted
1: Feeding/Moving Moving/Feeding
2: Moving/Feeding Moving/Feeding
3: Moving/Feeding Moving/Feeding
4: Moving/Feeding Moving/Feeding
5: Feeding/Moving Feeding/Moving
6: Feeding/Moving Feeding/Moving

#Calculating accuracy

> obs<-as.factor(test_accuracy$observed)
> pred<-as.factor(test_accuracy$predicted)
> mean(obs == pred)
[1] 0.8208556

我希望我足够清楚。我的问题是：是否可以使用一个函数来计算精度和召回率？如果没有，有人可以让我走上正确的道路来创建手动代码吗？我正在学习R，所以希望能得到一些帮助。
