# 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 |

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) |

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") |

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))) |

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.
