sin_d {aspace} | R Documentation |
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.
