R Introduction: Part I
Assignment Operators
Similar to some other programming languages, R has multiple assignment operators, which we can use interchangeably, at least for now.
In R, specific assignment operators such as <- and -> are available alongside the more universally recognized = operator. At this point, the difference between these operators is not significant, but we will revisit them later when we discuss functions.
Using <- for assignment is similar to using =, with the variable name positioned to the left and the value to the right. Conversely, the -> operator reverses this order. For instance, to assign the value 2020 to the variable year, there are three syntactical options:
r
Even though the last method of assignment is syntactically correct, it is generally discouraged due to its potential to reduce code readability.

- Use the 'equal' (
=) operator to assign the result of integer division of29by8to the variable namedequal. - Use the 'left-arrow' (
<-) operator to assign the remainder of the division of29by8to the variableleft. - Use the 'right-arrow' (
->) operator to assign theequalvariable raised to the power ofleftto therightvariable. - Display all three variable values in the order they were created with the
cat()function.
