We begin by loading in the Auto data set. This data is a data.frame created for the purpose of predicting sales volume. In these data, Sales is a continuous variable, and so we begin by recoding it as a binary Lets import the library. # Create Decision Tree classifier object. Carseats in the ISLR package is a simulated data set containing sales of child car seats at 400 different stores. It was found that the null values belong to row 247 and 248, so we will replace the same with the mean of all the values.

The square root of the MSE is therefore around 5.95, indicating How can this new ban on drag possibly be considered constitutional? If R says the Carseats data set is not found, you can try installing the package by issuing this command install.packages("ISLR") and then attempt to reload the data. for each split of the tree -- in other words, that bagging should be done. Trivially, you may obtain those datasets by downloading them from the web, either through the browser, via command line, using the wget tool, or using network libraries such as requests in Python.
