ob_point

Points are specified with x and y coordinates.

Polar points are ordinary points but are specified with an angle (theta) and a radial distance (r)

Usage

ob_point(
  x = 0,
  y = 0,
  alpha = numeric(0),
  color = character(0),
  fill = character(0),
  shape = numeric(0),
  size = numeric(0),
  stroke = numeric(0),
  style = S7::class_missing,
  id = character(0),
  ...
)

ob_polar(
  theta = S7::class_missing,
  r = numeric(0),
  alpha = numeric(0),
  color = character(0),
  fill = character(0),
  shape = numeric(0),
  size = numeric(0),
  stroke = numeric(0),
  style = S7::class_missing,
  id = character(0)
)

Arguments

x

Vector of coordinates on the x-axis (also can take a tibble/data.frame or 2-column matrix as input.)

y

Vector of coordinates on the y-axis

alpha

numeric value for alpha transparency

color

character string for color

fill

character string for fill color

shape

Point shape type. Can be specified with an integer (between 0 and 25), a single character (which uses that character as the plotting symbol), a . to draw the smallest rectangle that is visible (i.e., about one pixel), an NA to draw nothing, or a mapping to a discrete variable.

size

numeric size

stroke

Width of point border line

style

Gets and sets the styles associated with points

id

character string to identify object

...

<dynamic-dots> properties passed to style

theta

Angle of the vector from the origin to the ob_point

r

Radius = Distance from the origin to the ob_point

Value

ob_point object

Slots

auto_label

Gets x and y coordinates and makes a label "(x,y)"

geom

A function that converts the object to a geom. Any additional parameters are passed to ggplot2::geom_point.

length

The number of points in the ob_point object

tibble

Gets a tibble::tibble containing parameters and styles used by ggplot2::geom_point.

xy

Gets a 2-column matrix of the x and y coordinates of the ob_point object.

centroid

ob_point at the average of the x and y values

bounding_box

ob_rectangle that contains all the points in the object

place

function to place point in relation to other objects

label

function to create ob_label for points in the object

aesthetics

returns class_aesthetics for ob_point
