ggerror simplifies ggplot2’s error
geoms and introduces asymetric error bars and customization.
Instead of wiring ymin / ymax or
xmin / xmax by hand, you supply
error (or error_neg + error_pos)
and ggerror will do the rest for you. It can be as simple
as providing a single error argument, yet offer full
customization options for per-side styling.

library(ggplot2)
library(ggerror)
p <- ggplot(mtcars, aes(mpg, rownames(mtcars))) +
geom_point()
# Symmetric error bars, using default geom errorbar
p + geom_error(aes(error = drat))
# Asymmetric error bars, using geom_error_pointrange and per-side styling
p + geom_error_pointrange(aes(error_neg = drat / 2, error_pos = drat, linetype_neg = "dashed"))
# One-sided error bars, using the error_geom argument
p + geom_error(error_geom = "linerange", aes(error_neg = 0, error_pos = drat), width_neg = 0)
For detailed examples of symmetric, asymmetric, one-sided, and
per-side styling, see vignette("ggerror").
