Question

R3.6.1，vcdExtra 0.7.1

vcdExtra::datasets("caret")

get（x）中的错误：找不到对象'GermanCredit'

vcdExtra::datasets在“ caret”之类的某些程序包上失败。
我想念什么吗？谢谢

Answer 1

如果仅需要德语信用的数据集，请尝试以下代码：

library(caret)
data("GermanCredit")
GermanCredit

您将获得：

Answer 2

这是为了正确运行vcdExtra::datasets("caret")

而需要运行的命令序列

library(evtree)
library(caret)
data(Sacramento)
data(tecator)
data(BloodBrain)
data(cox2)
data(dhfr)
data(oil)
data(mdrr)
data(pottery)
data(scat)
data(segmentationData)
vcdExtra::datasets("caret")

输出为
