Introduction to R Programming

Lesson 3: Data Structures in R

Data structures are an essential part of any programming language, and R is no exception. In R, data structures can be divided into two main categories: atomic vectors and lists. Atomic vectors are a collection of elements of the same data type, while lists can contain elements of different data types.

There are four main types of atomic vectors in R: logical, integer, double, and character. Logical vectors can only contain TRUE or FALSE values. Integer vectors contain whole numbers, and double vectors contain decimal numbers. Character vectors contain strings of text.

Lists are a very flexible data structure in R, as they can contain elements of different data types. They can even contain other lists. Lists are created with the list() function.

Another important data structure in R is the data frame. A data frame is a table-like structure that contains rows and columns of data. Each column in a data frame can have a different data type. Data frames are created with the data.frame() function.

In summary, data structures are a fundamental aspect of R programming. Understanding the different types of data structures in R is essential to effectively organize and manipulate data in R. For further reading, I recommend the book "R for Data Science" by Hadley Wickham.
