Add ribbon

• add_sem_ribbon() adds the standard error of mean.

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

• add_sd_ribbon() adds the standard deviation.

• add_ci95_ribbon() adds the 95% confidence interval.

Usage

add_sem_ribbon(plot, dodge_width = NULL, alpha = 0.4, color = NA, ...)

add_range_ribbon(plot, dodge_width = NULL, alpha = 0.4, color = NA, ...)

add_sd_ribbon(plot, dodge_width = NULL, alpha = 0.4, color = NA, ...)

add_ci95_ribbon(plot, dodge_width = NULL, alpha = 0.4, color = NA, ...)

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.

alpha

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

color

A hex color for the stroke color. For example, "#FFFFFF" for white.

...

Arguments passed on to the geom function.

Value

A tidyplot object.
