Venn Diagram with Opacity in R (2 Examples)

 

In this R tutorial you’ll learn how to create a venn diagram with transparent colors.

It’s time to dive into the exemplifying R syntax.

 

Example 1: Venn Diagram with Transparent Color Shading Using VennDiagram Package

Example 1 explains how to create a transparent venn diagram using the VennDiagram package.

We first need to install and load the VennDiagram package, if we want to use the functions that are contained in the add-on package:

install.packages("VennDiagram")  # Install VennDiagram package
library("VennDiagram")           # Load VennDiagram package

Next, we can draw a colored venn diagram with opacity as shown below:

grid.newpage()                   # Create new plotting page
draw.pairwise.venn(area1 = 5,    # Draw pairwise venn diagram
                   area2 = 25,
                   cross.area = 2,
                   fill = 2:3)

 

VennDiagram

 

The venn diagram we have created with the previous R code is shown in Figure 1. As you can see, both circles are colored and the overlapping area is transparent.

 

Example 2: Venn Diagram with Transparent Color Shading Using venneuler Package

This example explains how to use the venneuler package to create a venn diagram with lowered alpha value.

First, we need to install and load the venneuler package:

install.packages("venneuler")    # Install & load venneuler
library("venneuler")

Now, we can apply the venneuler function in combination with the plot function as shown below:

plot(venneuler(c(A = 5,          # Draw pairwise venn diagram
                 B = 25,
                 "A&B" = 2)))

As shown in Figure 1, the previous R syntax has plotted a venn diagram with transparent colors.

I have recently published a video on my YouTube channel, which explains the R syntax of this tutorial. You can find the video below.

 

The YouTube video will be added soon.

In summary: In this article, I have explained how to draw transparent venn diagrams in the R programming language. If you have further questions, let me know in the comments.
