ob_line class — ob_line • ggdiagram

Creates a line

Usage

ob_line(
  slope = numeric(0),
  intercept = numeric(0),
  xintercept = numeric(0),
  a = numeric(0),
  b = numeric(0),
  c = numeric(0),
  alpha = numeric(0),
  color = character(0),
  lineend = numeric(0),
  linejoin = numeric(0),
  linewidth = numeric(0),
  linetype = numeric(0),
  style = S7::class_missing,
  id = character(0),
  ...
)

Arguments

slope: coefficient in y = slope * x + intercept
intercept: value of y when x is 0
xintercept: value of x when y is 0
a: coefficient in general form: a * x + b * y + c = 0
b: coefficient in general form: a * x + b * y + c = 0
c: constant in general form: a * x + b * y + c = 0
alpha: numeric value for alpha transparency
color: character string for color
lineend: Line end style (round, butt, square).
linejoin: Line join style (round, mitre, bevel).
linewidth: Width of lines
linetype: type of lines
style: an ob_style object
id: character string to identify object
...: <dynamic-dots> properties passed to style

Value

ob_line object

Additional properties

@aesthetics: A list of information about the circle's aesthetic properties
@angle: The angle of the line
@equation: Returns a character string with the equation for the line
@geom: A function that converts the object to a geom. Any additional parameters are passed to ggplot2::geom_line.
@length: The number of lines in the line object
@point_at_x: A function that finds the point on each line where x is equal to the x argument
@point_at_y: A function that finds the point on each line where y is equal to the y argument
@projection: A function that returns the projected point from the point object specified in p
@tibble: Returns a tibble (data frame) with object parameters, one row for each line in the line object
