R - AND OR Operators

AND

The & symbol (and) is a logical operator, and is used to combine conditional statements:

Test if a is greater than b, AND if c is greater than a:

a <- 200
b <- 33
c <- 500

if (a > b & c > a) {
print("Both conditions are true")
}

The | symbol (or) is a logical operator, and is used to combine conditional statements:

Test if a is greater than b, or if c is greater than a:

a <- 200
b <- 33
c <- 500

if (a > b | a > c) {
print("At least one of the conditions is true")
}
