The function geom_text() can be used to annotate on graphs in GGplot2. Geom_text() uses data frames to annotate. Other functions such as annotate() can also be used to annotate in GGplot2. The annotate() function is described in this other post. The dataset The following dataset is used below to illustrate how to annotate on a…
The Ggplot2 package can be used to create a bar graph with error bars. The geom_bar() function can be used to create the bar graph, and geom_errorbar() function can be used to add error-bars on the bar graph. We will use the dummy dataset (d_apples) below to create an example of a bar graph with…
Stacked Column Chart A stacked column chart also known as a stacked bar chart is a type of bar graph that stacks the categories of a group on top of each other. Each stack (category) is usually presented in a different color. The height of each stack is proportional to the percentages of that category….
Bar graphs, also known as Bar charts, are one of the most commonly used methods of visualizing grouped data. The length of each bar represents the magnitude of the data it is presenting. Bar graphs can be plotted horizontally or vertically. Bar graphs can easily be created in R using the ggplot2 package with the…
