Logical Operation is used for element-wise decision operations, which is based on specific operators between the operands which are then evaluated to either True or False Boolean value.
1. Element-wise Logical AND operator (&)
It returns True if both the operands are True.
Usage: a&b
2. Element-wise Logical OR operator (|)
It returns True if either of the operands is True.
Usage: a|b
3. NOT Operator (!)
It is used to negates the status of the elements of the operand.
Usage: !a
4. Logical AND Operator (&&)
It returns True if both the operands are True.
Usage: a&&b
5. Logical OR Operator (||)
It returns True if either of the operands is True.
Usage: a||b
Examples:
> list_1<-c(1,2,3)
> list_2<-c(2,3,4)
> print(list_1&list_2)
> print(list_1|list_2)
> print(!list_1)
> print(list_1&&list_2)
> print(list_1||list_2)
Output:
[1] TRUE TRUE TRUE
[1] TRUE TRUE TRUE
[1] FALSE FALSE FALSE
[1] TRUE
[1] TRUE
