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
p <- ob_point(0,0)
ob_circle(p, radius = 6)
#> <ob_circle>
#> @ center: <ob_point>
#> @ x: num 0
#> @ y: num 0
#> @ radius: num 6
