r - [R] VennDiagram 中的错误：“不可能……产生负面积”

Question

我无法使用 VennDiagram 创建绘图。以下是我的代码和错误：

venn.plot <- draw.quad.venn(area1 = 412, area2 = 471, area3 = 137, area4 = 1507, n12 = 11, n13 = 1, n14 = 132, n23 = 0, n24 = 183, n34 = 24, n123 = 1, n124 = 143, n134 = 18, n234 = 14, n1234 = 64, category = c("Set1", "Set2", "Set3", "Set4"), fill = c("orange", "red", "green", "blue"), lty = "dashed", cex = 2, cat.cex = 2, cat.col = c("orange", "red", "green", "blue"));

Error in draw.quad.venn(area1 = 412, area2 = 471, area3 = 137, area4 = 1507,  : 
Impossible: a5  <- n134 - a6 produces negative area

我检查了我的数学，但可能错过了什么？有什么想法吗？

Answer 1

问题是恕我直言，缺乏文档。尝试运行draw.triple.venn. 您将看到成对重叠区域中的值由参数值减去3 路参数值组成。那是，

venn.plot <- draw.triple.venn(
    area1 = 65,
    area2 = 75,
    area3 = 85,
    n12 = 35,
    n23 = 15,
    n13 = 25,
    n123 = 5)

在 2-way 区域中生成具有“30”、“20”、“10”的图。我怀疑你必须对你的输入值做同样的减法。
