Relational Operators

The Relational Operators in R carry out comparison operations between the corresponding elements of the operands. Returns a boolean TRUE value if the first operand satisfies the relation compared to the second. A TRUE value is always considered to be greater than the FALSE.

Less than (<)

Returns TRUE if the corresponding element of the first operand is less than that of the second operand. Else returns FALSE.

list1 <- c(TRUE, 0.1,"apple")
list2 <- c(0,0.1,"bat")
print(list1<list2)

Output :  FALSE FALSE  TRUE

Less than equal to (<=)

Returns TRUE if the corresponding element of the first operand is less than or equal to that of the second operand. Else returns FALSE.

list1 <- c(TRUE, 0.1, "apple")
list2 <- c(TRUE, 0.1, "bat")

# Convert lists to character strings
list1_char <- as.character(list1)
list2_char <- as.character(list2)

# Compare character strings
print(list1_char <= list2_char)

Output : TRUE TRUE TRUE

Greater than (>)

Returns TRUE if the corresponding element of the first operand is greater than that of the second operand. Else returns FALSE.

list1 <- c(TRUE, 0.1, "apple")
list2 <- c(TRUE, 0.1, "bat")
print(list1_char > list2_char)

Output : FALSE FALSE FALSE

Greater than equal to (>=)

Returns TRUE if the corresponding element of the first operand is greater or equal to that of the second operand. Else returns FALSE.

list1 <- c(TRUE, 0.1, "apple")
list2 <- c(TRUE, 0.1, "bat")
print(list1_char >= list2_char)

Output : TRUE TRUE FALSE

Not equal to (!=)

Returns TRUE if the corresponding element of the first operand is not equal to the second operand. Else returns FALSE.

list1 <- c(TRUE, 0.1,'apple')
list2 <- c(0,0.1,"bat")
print(list1!=list2)

Output : TRUE FALSE TRUE

The following R code illustrates the usage of all Relational Operators in R:

# R program to illustrate 
# the use of Relational operators
vec1 <- c(0, 2)
vec2 <- c(2, 3)

# Performing operations on Operands
cat ("Vector1 less than Vector2 :", vec1 < vec2, "\n")
cat ("Vector1 less than equal to Vector2 :", vec1 <= vec2, "\n")
cat ("Vector1 greater than Vector2 :", vec1 > vec2, "\n")
cat ("Vector1 greater than equal to Vector2 :", vec1 >= vec2, "\n")
cat ("Vector1 not equal to Vector2 :", vec1 != vec2, "\n")

Output

Vector1 less than Vector2 : TRUE TRUE 
Vector1 less than equal to Vector2 : TRUE TRUE 
Vector1 greater than Vector2 : FALSE FALSE 
Vector1 greater than equal to Vector2 : FALSE FALSE 
Vector1 not equal to Vector2 : TRUE TRUE

R Operators

Operators are the symbols directing the compiler to perform various kinds of operations between the operands. Operators simulate the various mathematical, logical, and decision operations performed on a set of Complex Numbers, Integers, and Numericals as input operands.
