# R Operators

##### There are the following types of operators in R.
• Arithmetic Operators
• Assignment Operators
• Logical Operators
• Comparison Operators
• Miscellaneous Operators

## Arithmetic Operators

Arithmetic operators work on only two numeric operands, if the operands are not numeric then it automatically converts to numeric.

 Operator Name Example + Addition v1 <- c(4, 5, 6)v2 <- c(1.4, 2.5, 3.2)print(v1+v2) - Subtraction v1 <- c(4, 5, 6)v2 <- c(1.4, 2.5, 3.2)print(v1-v2) * Multiplication v1 <- c(4, 5, 6)v2 <- c(1.4, 2.5, 3.2)print(v1*v2) / Division v1 <- c(4, 5, 6)v2 <- c(1.4, 2.5, 3.2)print(v1/v2) %% Modulus v1 <- c(4, 5, 6)v2 <- c(1.4, 2.5, 3.2)print(v1%%v2) %/% Integer Division v1 <- c(4, 5, 6)v2 <- c(1.4, 2.5, 3.2)print(v1%/%v2)

### Assignment Operators

Assignment operators assign a value to a variable, it assigns the value of its right operand to its left operand and also it can assigns the value of its left operand to its right operand.

 Operator Name Examples <-, <<-, = Leftwards assignment x <- 10 ->, ->> Rightwards assignment c(10, 3) -> y

### Logical Operators

These operators are used to perform logical operations. It returns the result in always a boolean value, it returns true if either or both operands are true and returns false otherwise.

 Operator Name Example & Element wise logical AND v1 <- c(4, 5, 6)v2 <- c(1.4, 2.5, 3.2)print(v1&v2) && Logical AND v1 <- c(4, 5, 6)v2 <- c(1.4, 2.5, 3.2)print(v1&&v2) | Element wise logical OR v1 <- c(4, 5, 6)v2 <- c(1.4, 2.5, 3.2)print(v1|v2) || Logical OR v1 <- c(4, 5, 6)v2 <- c(1.4, 2.5, 3.2)print(v1||v2) ! Logical NOT v1 <- c(4, 5, 6)print(!v1)

### Comparison Operators

Comparison operators are used for comparison and mostly used either in if conditions or loops. Its result is always a boolean value.

 Operator Name Example == Equal to v1 <- c(4, 5, 6)v2 <- c(4, 2.5, 6)print(v1==v2) != Not equal to v1 <- c(4, 5, 6)v2 <- c(4, 2.5, 6)print(v1!=v2) < Less than v1 <- c(4, 5, 6)v2 <- c(4, 2.5, 6)print(v1 < v2) > Greater than v1 <- c(4, 5, 6)v2 <- c(4, 2.5, 6)print(v1 > v2) >= Greater than equal to v1 <- c(4, 5, 6)v2 <- c(4, 2.5, 6)print(v1 >= v2) <= Less than equal to v1 <- c(4, 5, 6)v2 <- c(4, 2.5, 6)print(v1 <= v2)

### Miscellaneous Operators

 Operator Name Example : Colon Operator v <- 1:10 %in% Belongs to Operator v1 <- 4v2 <- 1:10print(v1 %in% v2) %*% Vector multiplication with its transpose M <- matrix(c(1,2,3), nrow=2, ncol=3, TRUE) print(M%*%t(M))

Colon Operator (:)- The colon operator generates a regular sequence, which is equivalent to interaction(a,b) but the levels are ordered and labelled differently.

Belongs to Operator (%in%) - The %in% operator identifies whether an element belongs to a vector or not.

Vector multiplication with its transpose (%*%) - The %*% operator performs multiplication of a vector with its transpose.
