Syntax: sign(x) Parameter: x represents numeric vector Returns: 1 for Positive number and -1 for Negative Number

Example 1:

r

# Create a variable
x <- 1
y <- -100

# Check sign
cat("Sign of x:", sign(x), "\n")
cat("Sign of y:", sign(y))

Output:

Sign of x: 1 
Sign of y: -1

Example 2:

r

# Creating a vector
x <- c(1, 5, 0, -10, 100, -20, 10, -69)

# Check Sign
cat("Sign of elements of vector x: ", sign(x), "\n")

Output:

Sign of elements of vector x:  1 1 0 -1 1 -1 1 -1
