Example R Notebook

A simple R example in the Notebook to test the installation of the R kernel functioned properly.

library(ggplot2)
library(randomForest)

Bring in the Iris dataset: - 150 observations, 50 each for 3 types of iris flowers - 4 features measuring length and width for sepals and petals

data(iris)
head(iris)

qplot(iris$Sepal.Length, geom='histogram')

Let’s fit a simple random forest model.

rf <- randomForest(Species ~ ., data=iris, importance=TRUE, proximity=TRUE)

Let’s check the accuracy of the model.

table(iris$Species, rf$predicted)
