ob_angle: ob_angle

In ggdiagram: Object-Oriented Diagram Plots with 'ggplot2'

ob_angle

Description

Creates an angle in the metric of radians, degrees, and turns.

Usage

ob_angle(
  .data = numeric(0),
  degree = numeric(0),
  radian = numeric(0),
  turn = numeric(0)
)

degree(degree = numeric(0))

radian(radian = numeric(0))

turn(turn = numeric(0))

Arguments

.data	a real number indicating the number of turns.
degree	degrees
radian	radians
turn	proportion of full turns of a circle (1 turn = 2 * pi radians)

Details

Angles turns can be any real number, but degrees are displayed as values between -360 and +360, and radians are between -2pi and +2pi.

Value

ob_angle

Slots

positive

if angle is negative, adds a full turn to ensure the angle is positive

negative

if angle is positive, subtracts a full turn to ensure the angle is negative

Examples

# Three Different ways to make a right angle
## 90 degrees
degree(90)

## half pi radians
radian(.5 * pi)

## A quarter turn
turn(.25)

# Operations
degree(30) + degree(20)
degree(350) + degree(20)
degree(30) - degree(30)
degree(30) - degree(50)

degree(30) * 2
degree(30) / 3

radian(1) + 1 # added or subtracted numbers are radians
degree(10) + 10 # added or subtracted numbers are degrees
turn(.25) + .25 # added or subtracted numbers are turns

# Trigonometric functions work as normal
sin(degree(30))
cos(degree(30))
tan(degree(30))
