ob_circle class

Description

ob_circle class

Usage

ob_circle(
  center = ob_point(0, 0),
  radius = 1,
  label = character(0),
  alpha = numeric(0),
  color = character(0),
  fill = character(0),
  linewidth = numeric(0),
  linetype = numeric(0),
  n = numeric(0),
  style = S7::class_missing,
  x = numeric(0),
  y = numeric(0),
  id = character(0),
  ...
)

Arguments

center	point at center of the circle
radius	distance between center and edge circle
label	A character, angle, or label object
alpha	numeric value for alpha transparency
color	character string for color
fill	character string for fill color
linewidth	Width of lines
linetype	type of lines
n	number of points in circle (default = 360)
style	an ob_style object
x	x-coordinate of center point. If specified, overrides x-coordinate of ⁠@center⁠.
y	x-coordinate of center point. If specified, overrides y-coordinate of ⁠@center⁠.
id	character string to identify object
...	<dynamic-dots> properties passed to style object

Value

ob_circle object

Slots

aesthetics

A list of information about the circle's aesthetic properties

angle_at

A function that finds the angle of the specified point in relation to the circle's center

area

area of the circle

bounding_box

a rectangle that contains all the circles

circumference

circumference of the circle

geom

A function that converts the object to a geom. Any additional parameters are passed to ggforce::geom_circle.

length

The number of circles in the circle object

normal_at

A function that finds a point that is perpendicular from the circle and at a specified distance

point_at

A function that finds a point on the circle at the specified angle.

polygon

a tibble containing information to create all the polygon points in a circle.

tangent_at

A function that finds the tangent line at the specified angle.

tibble

Gets a tibble (data.frame) containing parameters and styles used by ggforce::geom_cirlce.

Examples

# specify center point and radius
ob_circle(center = ob_point(0,0), radius = 6)
