add_sem_errorbar: Add error bar

Description

• add_sem_errorbar() adds the standard error of mean.

• add_range_errorbar() adds the range from smallest to largest value.

• add_sd_errorbar() adds the standard deviation.

• add_ci95_errorbar() adds the 95% confidence interval.

Usage

add_sem_errorbar(
  plot,
  dodge_width = NULL,
  width = 0.4,
  linewidth = 0.25,
  preserve = "total",
  ...
)
add_range_errorbar(
  plot,
  dodge_width = NULL,
  width = 0.4,
  linewidth = 0.25,
  preserve = "total",
  ...
)
add_sd_errorbar(
  plot,
  dodge_width = NULL,
  width = 0.4,
  linewidth = 0.25,
  preserve = "total",
  ...
)
add_ci95_errorbar(
  plot,
  dodge_width = NULL,
  width = 0.4,
  linewidth = 0.25,
  preserve = "total",
  ...
)

Value

A tidyplot object.

Arguments

plot

A tidyplot generated with the function tidyplot().

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.

width

Width of the plot area. Defaults to 50.

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.
