Convert degrees to radians

Tiny helper, used to disambiguate when the magnitude rule below would otherwise misclassify a small degree value as radians (e.g. if you actually want 5 degrees, write deg(5)).

Usage

deg(d)

Arguments

d

Numeric. Degrees.

Value

Numeric. Radians (d * pi / 180).

Examples

deg(45)   # 0.7853982
#> [1] 0.7853982
deg(180)  # 3.141593
#> [1] 3.141593
