In this post, we will learn how to make a barplot with error bar using ggplot2 in R. Barplot alone is useful to display counts for multiple categories. However, often there may be uncertainty around the count values and we could represent as error bar on the barplot. Let us … [Read more...] about How To Make Barplots with Error bars in ggplot2?

Coloring Barplots with ggplot2 in R
In this tutorial, we will see examples of making barplots and coloring the barplots in a few simple ways. We will see how to color barplots manually by specifying a color of interest and how to color a barplot by another variable in the dataset. Let us load tidyverse suite of … [Read more...] about Coloring Barplots with ggplot2 in R
How to Make Horizontal Stacked Barplots with ggplot2 in R?
Stacked barcharts are a variant of barplots, when you have data from multiple groups. In this tutorial, we will see two examples of making stacked barplots using ggplt2 in R. First we will see how to make stacked barplot of two groups with one on top of the other. In the second … [Read more...] about How to Make Horizontal Stacked Barplots with ggplot2 in R?
How to Reorder bars in barplot with ggplot2 in R
In this post, we will learn how to order bars in a barplot using ggplot2 in R. When we make barplot with ggplot2 on a character variable it places the group in alphabetical order. Here we will learn to use two functions, reorder() from base R and fct_reorder() function from … [Read more...] about How to Reorder bars in barplot with ggplot2 in R
