Arguments

• x: a list for plot
• main: Character giving the main title of the diagram
• color: color vector
• imagetype: Specification of the image format (e.g. tiff, png or svg)
• filename: Filename for image output, or if NULL returns the grid object itself
• lwd: width of the circle's circumference
• lty: dash pattern of the circle's circumference
• col: Colour of the circle's circumference
• fill: Colour of the circle's area
• cat.col: Colour of the category name
• cat.cex: size of the category name
• cat.dist: The distance (in npc units) of the category name from the edge of the circle (can be negative)
• rotation.degree: Number of degrees to rotate the entire diagram
• main.cex: Number giving the cex (font size) of the main title
• cex: size of the area label
• alpha: Alpha transparency of the circle's area
• reverse: logical,reflect the three-set Venn diagram along its central vertical axis of symmetry. Use in combination with rotation to generate all possible set orders
• ...: other parameters from venn.diagram

Returns

a venn plot according to x, y and.z named "name" paramter
