Description Objects from the Class Slots Extends Methods Author(s) Examples

A geometrical representation of a Venn diagram suitable for display

Objects can be created by calls of the form new("VennDrawing",V,TD) where V is an object of class Venn and TD is an object of class TissueDrawing which has representations for all the Sets and Faces corresponding to the sets and intersections of the V object.

As well as bringing together the geometric and set-theoretic properties of the Venn diagram, this class stores information about the universe in which to display the diagram and provides a number of methods for plotting the final figure.

universe:: A matrix with the x and y coordinates of the bounding universe. Currently assumed to have 2 rows by much of the code, corresponding to the lower left and upper right corners of a bounding rectangle
SetLabels:: A data.frame encoding the positions of labels for the Sets
FaceLabels:: A data.frame encoding the positions of labels for the Faces
setList:: See TissueDrawing-class
nodeList:: See TissueDrawing-class
recentChanges:: See TissueDrawing-class
edgeList:: See TissueDrawing-class
faceList:: See TissueDrawing-class

IndicatorWeight:: See Venn-class
