Information
Variables in R are akin to containers that hold data. They serve as the fundamental building blocks for any R program. You can think of a variable as a labeled storage location for a specific piece of information. Variables in R should be given informative names that reflect the type of data they store. For example, a variable named "age" might store the ages of individuals in a dataset.
In R, you declare a variable by assigning a value to it using the assignment operator <-. For example, to declare a variable "x" with a value of 5, you would write:
x <- 5
Variables can store data of different data types. For example, you can declare a character variable like this:
name <- "John"
Once a variable is declared, you can use it in your R code for various operations and calculations. The ability to manipulate variables is central to data analysis and programming in R.
