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.
