deg2rad: Degrees to Radians

Description

Transforms between angles in degrees and radians.

Usage

deg2rad(deg)
rad2deg(rad)

Arguments

deg

(array of) angles in degrees.

rad

(array of) angles in radians.

Value

The angle in degrees or radians.

Details

This is a simple calculation back and forth. Note that angles greater than 360 degrees are allowed and will be returned. This may appear incorrect but follows a corresponding discussion on Matlab Central.

Examples

Run this code

deg2rad(c(0, 10, 20, 30, 40, 50, 60, 70, 80, 90))
rad2deg(seq(-pi/2, pi/2, length = 19))
