sin_d: Compute sine with angle given in degrees

In aspace: Functions for Estimating Centrographic Statistics

Compute sine with angle given in degrees

Description

Provides the functionality of sin, but for input angles measured in degrees (not radians).

Usage

sin_d(theta = 0)

Arguments

theta

A numeric angular measurement in degrees from north.

Details

Since the R default is to compute trigonometric functions on angular measurements stored in radians, this simple function performs the conversion from degrees, reducing the need to do so a priori, outside the function.

Value

Returns a numeric value for the sine of the specified angular measurement

Note

To reduce the need for unit conversions prior to calling trigonometric functions, this function accepts input in angular degrees rather than radians. Depending on data, this function may be preferred to the existing version requiring input in angular radians.
