更改Venndiagram中数字的数字

Question

我不知道为什么但是当我使用VennDiagram包在维恩图可视化中使用数字时，重叠部分显示不同的数字位数，如下
我已经使用R和excel来计算这些数据（它们实际上是百分比）但是当我试图想象它时它们都给我这样的结果。

代码如下：

 draw.quintuple.venn(area1 = data[1,1],area2 = data[1,2],area3 = data[1,3],area4 = data[1,4],area5 = data[1,5],n12 = data[1,6],n13 = data[1,7],n14 = data[1,8],n15 = data[1,9],n23 = data[1,10],n24 = data[1,11],n25 = data[1,12],n34 = data[1,13],n35 = data[1,14],n45 = data[1,15],n123 = data[1,16],n124 = data[1,17],n125 = data[1,18],n134 = data[1,20],n135 = data[1,19],n145 = data[1,21],n234 = data[1,22],n235 = data[1,23],n245 = data[1,24],n345 = data[1,25],n1234 = data[1,26],n1235 = data[1,27],n1245 = data[1,28],n1345 = data[1,29],n2345 = data[1,30],
    n12345 = data[1,31],
    fill = c("#1f77b4", "#FF7F0E", "#2ca04e", "#d62728", "pink"),
    lwd = rep(1, 5),
    lty = "dashed",
    cex = 1,
    cat.cex = 2,
    cat.col =  c("#1f77b4", "#FF7F0E", "#2ca04e", "#d62728", "pink"))

数据是： data = as.data.frame(c(68.93,29.09, 2.85, 2.59, 13.86, 7.49, 1.12, 1.97, 4.84, 0.60, 0.34, 2.03, 0.13, 0.31, 0.29, 0.24, 0.27, 0.75, 0.15, 0.10, 0.23, 0.03, 0.09, 0.06, 0.02, 0.03, 0.05, 0.05, 0.02, 0.01, 0.01))
