In REdaS: Companion Package to the Book 'R: Einführung durch angewandte Statistik'

Description

Converts radians to degrees and vice versa.

Usage

deg2rad(d)

rad2deg(r)

Arguments

d	degrees
r	radians

Details

Since π rad = 180°, degrees (d) can be converted to radians (r) using r = d · π ∕ 180 and the conversion of radians to degrees is d = r · 180 ∕ π.
