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)
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.
