The “base R” method to create an R density plot. Before we get started, let’s load a few packages: library (ggplot2) library (dplyr) We’ll use ggplot2 to create some of our density plots later in this post, and we’ll be using a dataframe from dplyr. Now, let’s just create a simple density plot in R, using “base R”.

Line Plot using ggplot2 in R. In a line graph, we have the horizontal axis value through which the line will be ordered and connected using the vertical axis values. We are going to use the R package ggplot2 which has several layers in it. First, you need to install the ggplot2 package if it is not previously installed in R Studio.

Use geom_bar or geom_col and coord_polar to create pie charts in ggplot2. Add text and labels, customize the border, the color palette and the legend. Search for a graph.
R for Data Science is designed to give you a comprehensive introduction to the tidyverse, and these two chapters will get you up to speed with the essentials of ggplot2 as quickly as possible. If you’d like to take an online course, try Data Visualization in R With ggplot2 by Kara Woo.

The above code will automatically download the ggplot2 package, from the CRAN (Comprehensive R Archive Network) repository, and install it. Using ggplot2 After installing the package, you can load it using the R function library() .
