Sepal.Length Sepal.Width Petal.Length Petal.Width Species xĨd.Eliminate grammar errors and improve your writing with our free AI-powered grammar checker. Attach x to iris as dataframe “irisx”, check the head Create vector x which is the alternation of 1 and 2, 75 times, check the length Get the means of the first 2 columns in the “iris” dataset by SpeciesĨb. Get 2 vectors (index positions and absolute values) with all “lynx” observations smaller than 500 ( hint: which, subset) Create a vector of ordered “lynx” index numbers ( hint: order, increasing) The corresponding code is to be found on the solutions page. I will first write down the exercise question and below the question you can see how the console output should look like. The exercise solutions can be found here in an extra blog post.
On this sheet you will find 10 R exercises corresponding to the material taught in R Basics and R Level 1.
These R exercises are an add-on to the already existing exercise videos available in each and every R-Tutorial product.
Therefore, I decided to write an R exercise sheet for beginners and blog it over here. Many of my students think the same and would love to see more exercises.
Statistical languages like R are no exception of that rule. Practicing is a crucial part of learning a new language.
