discern

discern,Venn-method

<code>discern</code> returns the difference between two group of sets selected from
 a <code>Venn</code> object. If multiple sets are chosen for the slices, union of
 those sets will be used.

Easy-to-use functions to generate 2-7 sets Venn or upset plot in publication quality.
'ggVennDiagram' plot Venn or upset using well-defined geometry dataset and 'ggplot2'. The shapes of 2-4 sets
Venn use circles and ellipses, while the shapes of 4-7 sets Venn use irregular polygons (4 has both forms), which
are developed and imported from another package 'venn', authored by Adrian Dusa. We provided internal functions to
integrate shape data with user provided sets data, and calculated the geometry of every regions/intersections
of them, then separately plot Venn in four components: set edges/labels, and region edges/labels.
From version 1.0, it is possible to customize these components as you demand in ordinary 'ggplot2' grammar.
From version 1.4.4, it supports unlimited number of sets, as it can draw a plain upset plot automatically when
number of sets is more than 7.
