A helper function to calculate vector lengths

Calculates the length of a vector using the Pythagorean theorem.

Usage

pythagoras(x, y)

Arguments

x

A numeric vector with the same length as y. It should represent the lengths of the first leg (cathetus) of right triangles.

y

A numeric vector with the same length as x. It should represent the lengths of the second leg (cathetus) of right triangles.

Value

Returns a numeric vector with the same length as x and y, reflecting the lengths of the hypotenuse of the right triangles.
