You want to save a value in a variable.
To save a value in a variable we define the name of the variable followed by the assignment operator (<-) and the value of the variable. The assignment operator is made of a less-than character(<) and a hyphen(-) with no space between them.
Let’s say you want to create two variables and add them together.
> a <- 5 > b <- 10 > c <- a + b > print(c)  15
We can also check the value of a variable by typing it in the console.
> a  5 > b  10 > c  15
