chebyshev: Chebyshev distance

Description

The Chebyshev distance is the maximum absolute difference between the vector elements.

Usage

chebyshev(x, y)

Arguments

x, y

Numeric vectors

Value

The Chebyshev distance between x and y.

Details

For vectors x and y, the Chebyshev distance is defined as $$d(x, y) = \max_i |x_i - y_i|.$$ Relation to other definitions:

• Equivalent to the chebyshev() function in scipy.spatial.distance.

Examples

# NOT RUN {
x <- c(15, 6, 4, 0, 3, 0)
y <- c(10, 2, 0, 1, 1, 0)
chebyshev(x, y) # should be 5
# }
