nVennR2: nVennR2

In nVennR2: An Interface to 'nVenn2'

nVennR2

Description

An interface to nVenn2 to create n-dimensional, quasi-proportional Venn diagrams.

Details

The input for nVennR2 is a list of lists or a text table. The dataset exampledf contains an example of a list of lists, where each internal list has a name for the set and some set elements. The result will be a Venn diagram where each region is represented by a circle whose area is approximately proportional to the number of elements in that region. Each circle has two labels. The number in a larger font size represents the number of elements in the region. The smaller numbers in parentheses show which sets the region belongs to.

A diagram is created with nVennDiagram() and plotted and/or saved with plotVenn(). The appearance of the plot can be changed with setVennOpts() and setVennColors(). If a plot is saved, the resulting svg file can be loaded again with readVennSVG().

Value

nVennObj. An nVenn object with the information needed to represent and edit the diagram, and to explore its regions.
