3.7 Operators
20210103 The third type of function is the operator. We use operators in the flow of an expression. Technically they are called infix operators.
In the following example we use the base::+ infix operator.
## [1] 3Internally R actually converts the operator into a functional prefix form to be run in the same way as any other function.
## [1] 3Note that R also supports using quotes and double quotes instead of the backtick we used in the code above. The backtick is preferred as per page 142 of Wickham (2014).
The key thing to remember is that all commands and operators are functions and we instruct R to take action by running functions.
