无法从R AppliedPredictIctiveModeling软件包访问CARS2010数据帧

Question

我正在尝试访问R AppliedPredictiCtiveModeling软件包中列出的CARS2010数据帧：

这是数据的部分输出（package =" appliedpredictivemodeling"）命令：

Data sets in package ‘AppliedPredictiveModeling’:
ChemicalManufacturingProcess
                 Chemical Manufacturing Process
                 Data
abalone          Abalone Data
bio (hepatic)    Hepatic Injury Data
cars2010 (FuelEconomy)
                 Fuel Economy Data
cars2011 (FuelEconomy)
                 Fuel Economy Data
cars2012 (FuelEconomy)
                 Fuel Economy Data

我能够访问软件包中的另一个数据框：分割式的，但不是CARS201X DataFrames

> library(AppliedPredictiveModeling)
> data(cars2010)
Warning message:
In data(cars2010) : data set ‘cars2010’ not found
> data(segmentationOriginal)
> data(cars2011)
Warning message:
In data(cars2011) : data set ‘cars2011’ not found
> data(cars2012)
Warning message:
In data(cars2012) : data set ‘cars2012’ not found

您知道这一点的解释吗？我确实有最新的软件包-1.1.6

谢谢
