&& Operator in R
The “&&” operator is the “logical AND” operator. It is used to evaluate two logical expressions and return a single logical value indicating whether both expressions are TRUE or not.
R
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"
Now let’s look at one more example using the “&&” operator.
R
# "&" operator x <- 7 y <- 11 z <- 17 x < y & y < z # "&" operator x < y && y < z |
Output:
TRUE TRUE
Difference Between & and && in R
In R Programming Language, “&” and “&&” are two logical operators used to combine logical expressions. However, they behave differently in terms of how they evaluate expressions and return results.
The “&” operator evaluates both expressions and returns a vector of the same length as the inputs, where each element is the result of a logical “and” operation. This means that it returns TRUE only if both expressions are TRUE and FALSE.
- The “&” operator performs the element-wise comparison and returns a logical vector of the same length as its input.
- the “&&” operator evaluates only the first element of the input and returns the single logical value.
The “&” and “&&” operators are used for logical operations. The &” and “&&” are two logical operators used to evaluate logical expressions.
