R Operators
Operators are used to perform operations on variables and values.
1) Arithmetic operators are used with numeric values to perform common mathematical operations.

2) Assignment operators are used to assign values to variables.
my_var <- 3
my_var <<- 3
3 -> my_var
3 ->> my_var
## x <- 3 is equal to 3 -> x
## Note: <<- is a global assigner.
3) Comparison operators are used to compare two values.
Comparison Operators

Name
Example
==
Equal
x == y
!=
Not equal
x != y
>
Greater than
x > y
<
Less than
x < y
>=
Greater than or equal to
x >= y
<=
Less than or equal to
x <= y

4) Logical operators are used to combine conditional statements.
Logical Operators
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

x <- c(TRUE, FALSE, TRUE)
y <- c(FALSE, TRUE, TRUE)
x & y
## Output:
[1] FALSE FALSE TRUE
x <- 5
if (x > 0 && x < 10)
{
print("x is positive and less than 10")
}
else
{
print("x is either negative or greater than 10")
}
## Output:
[1] "x is positive and less than 10"
5) Miscellaneous operators are used to manipulate data
Miscellaneous Operators
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
