toCartesianXY: Computes the x,y cartesian coordinates

Description Usage Arguments Value Note

View source: R/math.R

Description

Computes the x and y cartesian coordinates from a set of polar coordinates

Usage

1
toCartesianXY(angle, distance)

Arguments

angle

The angle in degrees (measured clockwise from the North or any other relevant bearing system defined in the field)

distance

The distance

Value

A vector holding the x and y coordinats expressed in the same unit as the distance argument

Note

The function assumes the angle is measured clockwise whereas trigonometric functions require a conventional counterclockwise measured angle. Thus the function computes x coordinate as the sine of the angle, and the y coordinate as the cosine of the angle, enabling a correct representation of them on a cartesian plot.
