How to create PIE chart in R

A pie chart, is a circular statistical graphic which is divided into slices to illustrate numerical proportion. It is a useful tool for visualizing relative proportions of different categories within a dataset. In this blog post, we will discuss how to create pie charts in R.

The most basic way to create a pie chart in R is by using the pie() function. This function takes a single vector of data as an argument and creates a pie chart of the data. The function also takes several other arguments that can be used to customize the appearance of the plot, such as the colors of the slices and the main title.

Another way to create a pie chart in R is by using the ggplot2 package. This package provides a powerful and flexible way to create pie charts and other types of plots. To create a pie chart using ggplot2, you first need to create a ggplot() object and then add a geom_bar(stat = "identity") and coord_polar("y", start = 0) layer to the object. The geom_bar(stat = "identity") and coord_polar("y", start = 0) layers takes several arguments that can be used to customize the appearance of the plot, such as the colors of the slices, the size of the slices and the main title.

In addition to the above methods, you can also create pie charts using other packages like plotly which provide more advanced functionalities.
