Egzersiz talimatları
- Load the
randomForestpackage. - Use the
set.seed()function with the seed 863. - Build a random forest using the function
randomForest()and all the variables intraining_set. The response variableFutureneeds to be a factor, so utilize theas.factor()function. - Plot the variable importance of the random forest model using
varImpPlot().
