In R, you can use operators to perform common mathematical operations on numbers
In R, you can use operators to perform common mathematical operations on numbers.
The + operator is used to add together two values:
10 + 5
And the - operator is used for subtraction:
10 - 5
You will learn more about available operators in our R Operators Tutorial.
R also has many built-in math functions that allows you to perform mathematical tasks on numbers.
For example, the min() and max() functions can be used to find the lowest or highest
number in a set:
max(5, 10, 15)
min(5, 10, 15)
The sqrt() function returns the square root of
a number:
sqrt(16)
The abs() function returns the absolute (positive) value of
a number:
abs(-4.7)
The ceiling() function rounds a number upwards to
its nearest integer, and the floor()
function rounds a number downwards to its nearest integer, and returns the result:
ceiling(1.4)
floor(1.4)
