A
Venn diagram
(also called primary diagram, set diagram or logic diagram) is a
diagram that shows all possible logical relations between a finite
collection of different sets. In R, the
`VennDiagram`

package is the best option to build one. Note
that with more than 3 sets, it is better to switch to an
`upsetChart`

, as described below.

Step by step - the

`VennDiagram`

package
The `VennDiagram`

package is the best way to build Venn
Diagrams in `R`

. The 3 examples below will guide you
through its functioning, from basic examples to customized charts.

Switch to the upsetChart with

`UpSetR`

An Upset plot is an alternative to the Venn Diagram used to deal with
more than 3 sets. Indeed, a classic Venn Diagram gets to cluttered and
unreadable with four groups or more. The upSet plot is built in
`R`

thanks to the `upSetR`

package.
