R Booleans

Used to represent the truth or false values of a varaible or for a condition.
Generally used in conditional statements and logical operations.
Denoted by the values TRUE and FALSE

# Boolean variables
is_true <- TRUE
is_false <- FALSE

Comparison Operators

Used to compare values and return Boolean values.

# Comparison operators
a <- 5
b <- 10

# Equality
is_equal <- a == b  # FALSE

# Inequality
not_equal <- a != b  # TRUE

# Greater than
greater_than <- a > b  # FALSE

# Less than
less_than <- a < b  # TRUE

# Greater than or equal to
greater_equal <- a >= b  # FALSE

# Less than or equal to
less_equal <- a <= b  # TRUE

Logical Operators

Combine's one or more Boolean values and gives a final result.

# Logical operators
x <- TRUE
y <- FALSE

# AND
result_and <- x & y  # FALSE

# OR
result_or <- x | y  # TRUE

# NOT
result_not <- !x  # FALSE

result_or & result_and & result_not
result_or | result_and & result_not
result_or & result_and | result_not
result_or | result_and | result_not

Conditional Statements

Boolean values are commenly used in conditional statements.
They are used to check the condition and return true or false to execute a block of code in the conditional statements.

# If statement
if (is_true) {
  print("It's true!")
} else {
  print("It's false!")
}
