R Equal-To Operator
R – Equal-To Operator ==
is used to check if its two operands are exactly equal to each other.
==
symbol is used for Equal-To Operator in R Language.
The syntax of Equal-To Operator with the two operands is
operand1 == operand2
Equal-To Operator takes two operands and returns a boolean value of TRUE if the two operands are exactly equal to each other, or FALSE otherwise.
Examples
Check If Two Boolean Values are Equal
In the following R program, we will take two boolean values and check if they are equal using Equal-To Operator.
example.r
x <- TRUE
y <- TRUE
result <- x == y
cat(x, "==", y, " is ", result, "\n")
x <- TRUE
y <- FALSE
result <- x == y
cat(x, "==", y, " is ", result, "\n")
Output
tutorialkart$ Rscript example.r
TRUE == TRUE is TRUE
TRUE == FALSE is FALSE
Check If Two String Values are Equal
In the following R program, we will take two string values and check if they are equal using Equal-To Operator.
example.r
x <- "apple"
y <- "banana"
result <- x == y
cat(x, "==", y, " is ", result, "\n")
x <- "apple"
y <- "apple"
result <- x == y
cat(x, "==", y, " is ", result, "\n")
Output
apple == banana is FALSE
apple == apple is TRUE
Check If Two Numbers are Equal
In the following R program, we will take two numbers in x
and y
, and check if they are equal using Equal-To Operator.
example.r
x <- 3
y <- 4
result <- x == y
cat(x, "==", y, " is ", result, "\n")
x <- 2
y <- 2
result <- x == y
cat(x, "==", y, " is ", result, "\n")
Output
3 == 4 is FALSE
2 == 2 is TRUE
Conclusion
Concluding this R Tutorial, we learned what R Equal-To Operator is, and how to use it to check if two objects or values are exactly equal.
