如何格式化confusionMatrix插入符号包

Question

使用R中插入符号包中的confusionMatrix()函数，如何垂直格式化输出？

我目前的输出如下：

$positive
[1] "spam"

$table
          Reference
Prediction  ham spam
      ham  1201   30
      spam    6  153

$mode
[1] "sens_spec"

我想要像：

Accuracy:
95% CI
No Information Rate:
P-Value [Acc > NIR]:

Kappa:
Mcnemar's Test P-Value:

Sensitivity:
Specificity:
Pos Pred Value:
Neg Pred Value:
Prevalence:
Detection Rate:
Detection Prevalence:
Balanced Accuracy:

Answer 1

试试这个：

t(confusionMatrix()$byClass)

和此：

confusionMatrix()$overall

根据您的数据类别数量，您可以对其进行判断
