vennDiagram2: Venn Diagrams

In drmjc/mjcgraphics: mjc's graphics library

Description

Plot classification counts in Venn diagram. This is a replacement for vennDiagram from limma, with xlim and ylim changed in the plot call, and mar=par("mar") to get rid of all of the whitespace around the box

Usage

  vennDiagram2(object, include = "both", names,
    mar = par("mar"), cex = 1.5,
    circle.colours = rep("black", 10),
    text.colours = rep("black", 10), ...)

Arguments

object	either a TestResults matrix or a VennCounts object produced by vennCounts.
include	character string, of length one or two, specifying whether the diagram should give counts for genes up-regulated, down-regulated or both. See details. Choices are “both”, “up” or “down”.
names	optional character vector giving names for the sets or contrasts
mar	numeric vector of length 4 specifying the width of the margins around the plot. This argument is passed to par. default = par("mar")
cex	numerical value giving the amount by which the contrast names should be scaled on the plot relative to the default.plotting text. See par. default = cex = 1.5
circle.colours	optional vector of color specifications defining the colors by which the circles should be drawn. See par. default =rep("black", 10)
text.colours	optional vector of color specifications, of same length as include, defining the colors by which the counts should be drawn. See par. default=rep("black", 10)
...	further arguments passed to vennDiagram

Value

none.
