tidyplots (version 0.2.1)

add_line: Add line or area

Description

add_line() and add_area() connect individual data points, which is rarely needed. In most cases, you are probably looking for add_sum_line(), add_mean_line(), add_sum_area() or add_mean_area().

Usage

add_line(
  plot,
  group,
  dodge_width = NULL,
  linewidth = 0.25,
  preserve = "total",
  ...
)
add_area(
  plot,
  group,
  dodge_width = NULL,
  linewidth = 0.25,
  alpha = 0.4,
  preserve = "total",
  ...
)

Value

A tidyplot object.

Arguments

plot

A tidyplot generated with the function tidyplot().

group

Variable in the dataset to be used for grouping.

dodge_width

For adjusting the distance between grouped objects. Defaults to 0.8 for plots with at least one discrete axis and 0 for plots with two continuous axes.

linewidth

Thickness of the line in points (pt). Typical values range between 0.25 and 1.

preserve

Should dodging preserve the "total" width of all elements at a position, or the width of a "single" element?

...

Arguments passed on to the geom function.

alpha

A number between 0 and 1 for the opacity of an object. A value of 0 is completely transparent, 1 is completely opaque.

Examples

# Paired data points
study %>%
  tidyplot(x = treatment, y = score, color = group) %>%
  reorder_x_axis_labels("A", "C", "B", "D") %>%
  add_data_points() %>%
  add_line(group = participant, color = "grey")

study %>%
  tidyplot(x = treatment, y = score) %>%
  reorder_x_axis_labels("A", "C", "B", "D") %>%
  add_data_points() %>%
  add_area(group = participant)
