Add reference lines

Usage

add_reference_lines(
  plot,
  x = NULL,
  y = NULL,
  linetype = "dashed",
  linewidth = 0.25,
  ...
)

Arguments

plot: A tidyplot generated with the function tidyplot().
x: Numeric values where the reference lines should meet the x-axis. For example, x = 4 or x = c(2,3,4).
y: Numeric values where the reference lines should meet the y-axis. For example, y = 4 or y = c(2,3,4).
linetype: Either an integer (0-6) or a name (0 = blank, 1 = solid, 2 = dashed, 3 = dotted, 4 = dotdash, 5 = longdash, 6 = twodash).
linewidth: Thickness of the line in points (pt). Typical values range between 0.25 and 1.
...: Arguments passed on to the geom function.

Value

A tidyplot object.

Examples

animals %>%
  tidyplot(x = weight, y = speed) %>%
   add_reference_lines(x = 4000, y = c(100, 200)) %>%
   add_data_points()


animals %>%
  tidyplot(x = weight, y = speed) %>%
   add_reference_lines(x = 4000, y = c(100, 200), linetype = "dotdash") %>%
   add_data_points()
