| Operator | Description |
|---|---|
| abs(x) | Takes the absolute value of x |
| log(x,base=y) | Takes the logarithm of x with base y; if base is not specified, returns the natural logarithm |
| exp(x) | Returns the exponential of x |

What are functions in your programming?
R has a large number of in-built functions and the user can create their own functions. In R, a function is an object so the R interpreter is able to pass control to the function, along with arguments that may be necessary for the function to accomplish the actions.
