Venn Diagrams
维恩图
译者：生物统计家园网 机器人LoveR
描述----------Description----------
Compute classification counts or plot classification counts in a Venn diagram.
计算在维恩图分类计数或图分类计数。
用法----------Usage----------
vennCounts(x, include="both")
vennDiagram(object, include="both", names, mar=rep(1,4), cex=1.5, lwd=1,
circle.col, counts.col, show.include, ...)
参数----------Arguments----------
参数：x
numeric matrix of 0's and 1's indicating significance of a test. Usually created by decideTests.
数字矩阵的0和1的指示意义的测试。通常创建decideTests。
参数：object
either a TestResults matrix or a VennCounts object produced by vennCounts.
要么TestResults矩阵或生产VennCountsvennCounts对象。
参数：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".
字符串，长度为一个或两个指定的图是否应给予上调，下调基因或两者的罪名。查看详情。选择是"both"，"up"或"down"。
参数：names
optional character vector giving names for the sets or contrasts
可选的特征向量套或对比的名称
参数：mar
numeric vector of length 4 specifying the width of the margins around the plot. This argument is passed to par.
长度为4的数字矢量指定宽度的边缘周围的图。这个参数被传递到par。
参数：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.
数值给人，对比度名称应缩放相对的default.plotting文本图的金额。看到par。
参数：lwd
numerical value giving the amount by which the circles should be scaled on the plot. See par.
使圆应图缩放量的数值。看到par。
参数：circle.col
optional vector of color specifications defining the colors by which the circles should be drawn. See par.
可选的颜色规格定义颜色的各界应提请向量。看到par。
参数：counts.col
optional vector of color specifications, of same length as include, defining the colors by which the counts should be drawn. See par.
可选颜色规格的矢量长度相同，include，确定应当制定计数的颜色。看到par。
参数：show.include
logical value whether the value of include should be printed on the plot. Defaults to FALSE if include is a single value and TRUE otherwise
include价值是否应图上印的逻辑值。默认FALSE如果include是一个单一的价值和TRUE否则
参数：...
any other arguments are passed to plot
任何其他参数传递plot的
Details
详情----------Details----------
If a vennCounts object is given to vennDiagram, the include parameter is ignored. If a TestResults object is given, then it is possible to set include as a vector of 2 character strings and both will be shown.
如果vennCounts对象vennDiagram，include参数将被忽略。如果TestResults对象，那么它是可以设置include2个字符的字符串作为向量，都将被显示。
值----------Value----------
vennCounts produces a VennCounts object, which is a numeric matrix with last column "Counts" giving counts for each possible vector outcome. vennDiagram causes a plot to be produced on the current graphical device. For venDiagram, the number of columns of object should be three or fewer.
vennCounts生产VennCounts对象，这是最后一列"Counts"给每一个可能的向量结果计数的数字矩阵。 vennDiagram导致图在当前的图形设备。 venDiagram，列数object应该是三个或更少。

举例----------Examples----------
Y <- matrix(rnorm(100*6),100,6)
Y[1:10,3:4] <- Y[1:10,3:4]+3
Y[1:20,5:6] <- Y[1:20,5:6]+3
design <- cbind(1,c(0,0,1,1,0,0),c(0,0,0,0,1,1))
fit <- eBayes(lmFit(Y,design))
results <- decideTests(fit)
a <- vennCounts(results)
print(a)
vennDiagram(a)
vennDiagram(results,include=c("up","down"),counts.col=c("red","green"))
