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.
This article describes how to easily create barplots with error bars in R using the ggpubr package, an extension of ggplot2 for creating publication ready plots. The following R code produces barplots showing means +/- sd and the jittered data points for each group. library(ggpubr) # ...

在SCI论文的数据图表中，作者习惯于用条形图来表示分类数据的分布特征。在ggplot2中，条柱对应的几何对象函数为 geom_bar() , 它的功能就是展示 计数数据 ，即每种分类水平一共有多少个观测值。在ggplot2中，通常使用的条柱排列方式有三种，并排式（dodge）、堆栈式（stack）和填充式（fill）。 ...
Figure 7: Barchart Created with ggplot2 Package. Figure 7 shows bars with the same values as in Examples 1-4. However, this time the bargraph is shown in the typical ggplot2 design. Example 8: Barplot in plotly Package Another powerful R add-on package for the printing of barcharts is...
After this, we construct a ggplot object that contains information about the data frame we’re using as well as the x and y variables. From there it’s a simple matter of plotting our data as a barplot (geom_bar()) with error bars (geom_errorbar())! library(ggplot2) dodge <- posi...
The output of the previous R syntax is shown in Figure 1 – A barplot with only one color.Example 1: Drawing ggplot2 Barplot with Default ColorsThe following syntax shows how to create a barchart with a different color for each of the bars using the default ggplot2 color palette....
