If you have experience programming in another language, you may be familiar with lists, but if not, don't worry! You can create a list in R using the list() function, as shown in the following example: L1 <- list(1, "2", "Hello", "cat", 12, list(1, 2, 3)) Let's walk ...
Learn how to efficiently access elements of nested lists in R with step-by-step examples and explanations.
There are many occasions in computing when it is necessary to deal with tables (referred to in other programming languages as arrays ), and we shall be looking at them in detail in the next chapter. However, in this chapter we shall be looking at lists — a list being a special case ...
In this post, we will show how to create vectors, factors, lists, matrices and datasets in R Vectors The vector is a very important tool in R programming. Through vectors, we create matrix and data frames. Vectors can have numeric, character and logical values. The function c() is used...

Predictive models generated by modern machine learning algorithms, such as deep neural networks, tend to be complex and difficult to comprehend, and may not be appropriate in applications where a certain degree of transparency of a model and explainability of decisions are desirable. Besides, dependin...
In today’s article, I am going to talk about R programming language that was originally developed by and for statisticians and then became widely accepted by data scientists as well. In the first part of this two-part introduction to R, we are going to consider: · What is R and how ...

Outside-In TDD is sometimes called “programming by wishful thinking”, and you can see why. We start writing code at the higher levels based on what we wish we had at the lower levels, even though it doesn’t exist yet! We can rerun our FTs, to check we didn’t break anything,...
