Ggplot2 Charts R Graphs Bar Charts With Error Bars In Ggplot2 Library(ggplot2) ggplot(diamonds, aes(cut, price, fill = color)) stat summary(geom = "bar", fun = mean, position = "dodge") stat summary(geom = "errorbar", fun.data = mean se, position = "dodge") if you prefer to calculate the values beforehand, you could do it like this: library(tidyverse) pdata < diamonds %>%. This post describes how to add error bars on your barplot using r. both ggplot2 and base r solutions are considered. a focus on different types of error bar calculation is made.
