To split the carseats dataset from the islr library into a training dataset and a testing dataset, you can use the sample() function in R.
How to split the dataset?you could use the following code to split the dataset into a random 60% training dataset and a 40% testing dataset:
# Load the islr library
library(islr)
# Load the carseats dataset
data(carseats)
# Split the dataset into training and testing sets
train_idx <- sample(nrow(carseats), size = 0.6 * nrow(carseats))
train <- carseats[train_idx, ]
test <- carseats[-train_idx, ]
Once you have split the dataset, you can use the tree() function to fit a regression tree to the training set. The response variable will be sales. For example, you could use the following code:
# Fit a regression tree to the training set
model <- tree(sales ~ ., data = train)
This will fit a regression tree to the training dataset, using all of the other variables in the dataset as predictors for the sales variable. You can then use this model to make predictions on the testing dataset and evaluate its performance
