In the example below, we use the + operator to add together two values: Example 10 + 5 Try it Yourself » R divides the operators in the following groups: Arithmetic operators Assignment operators Comparison operators Logical operators Miscellaneous operators R Arithmetic Operators Arithmetic operators are used with numeric values to perform common mathematical operations: Operator Name Example Try it + Addition x + y Try it » - Subtraction x - y Try it » * Multiplication x * y Try it » / Division x / y Try it » ^ Exponent x ^ y Try it » %% Modulus (Remainder from division) x %% y Try it » %/% Integer Division x%/%y Try it » R Assignment Operators Assignment operators are used to assign values to variables: Example my_var <- 3 my_var <<- 3 3 -> my_var 3 ->> my_var my_var # print my_var Try it Yourself » Note: <<- is a global assigner. You will learn more about this in the Global Variable chapter . It is also possible to turn the direction of the assignment operator. x <- 3 is equal to 3 -> x R Comparison Operators Comparison operators are used to compare two values: Operator Name Example Try it == Equal x == y Try it » != Not equal x != y Try it » > Greater than x > y Try it » < Less than x < y Try it » >= Greater than or equal to x >= y Try it » <= Less than or equal to x <= y Try it » R Logical Operators Logical operators are used to combine conditional statements: Operator Description & Element-wise Logical AND operator. Returns TRUE if both elements are TRUE && Logical AND operator - Returns TRUE if both statements are TRUE | Elementwise- Logical OR operator. Returns TRUE if one of the statements is TRUE || Logical OR operator. Returns TRUE if one of the statements is TRUE ! Logical NOT - Returns FALSE if statement is TRUE R Miscellaneous Operators Miscellaneous operators are used to manipulate data: Operator Description Example : Creates a series of numbers in a sequence x <- 1:10 %in% Find out if an element belongs to a vector x %in% y %*% Matrix Multiplication x <- Matrix1 %*% Matrix2 Note: You will learn more about Matrix multiplication and matrices in a later chapter. ❮ Previous Next ❯ ★ +1 Sign in to track progress COLOR PICKER REMOVE ADS PLUS SPACES GET CERTIFIED FOR TEACHERS BOOTCAMPS CONTACT US × Contact Sales If you want to use W3Schools services as an educational institution, team or enterprise, send us an e-mail: [email protected] Report Error If you want to report an error, or if you want to make a suggestion, send us an e-mail: [email protected] Top Tutorials HTML Tutorial CSS Tutorial JavaScript Tutorial How To Tutorial SQL Tutorial Python Tutorial W3.CSS Tutorial Bootstrap Tutorial PHP Tutorial Java Tutorial C++ Tutorial jQuery Tutorial Top References HTML Reference CSS Reference JavaScript Reference SQL Reference Python Reference W3.CSS Reference Bootstrap Reference PHP Reference HTML Colors Java Reference AngularJS Reference jQuery Reference Top Examples HTML Examples CSS Examples JavaScript Examples How To Examples SQL Examples Python Examples W3.CSS Examples Bootstrap Examples PHP Examples Java Examples XML Examples jQuery Examples Get Certified HTML Certificate CSS Certificate JavaScript Certificate Front End Certificate SQL Certificate Python Certificate PHP Certificate jQuery Certificate Java Certificate C++ Certificate C# Certificate XML Certificate     FORUM ABOUT ACADEMY W3Schools is optimized for learning and training.
