PlotCirc (DescTools包)中的标签旋转

Question

我正在使用DescTools R包的R函数来可视化一个应急表：

library(DescTools)

tab <- matrix(c(2,5,8,3,10,12,5,7,15), nrow=3, byrow=FALSE)
dimnames(tab) <- list(c("ABCDEFG","BCDEFGH","CDEFGHI"), c("D","E","F"))

PlotCirc( tab,
          acol = c("dodgerblue","seagreen2","limegreen","olivedrab2","goldenrod2","tomato2"),
          rcol = SetAlpha(c("red","orange","olivedrab1"), 0.5)
)

​

​

问题：

我如何旋转所有标签(左和右)，使它们从圆圈(指向圆心的文本基线)传播？也就是说，第一个标签"ABCDEFG“应该旋转近-90度指向向上，而"CDEFGHI”应该旋转大约45度，指向一点向下等等。

Answer 1

DescTools v0.99.8现在提供了一个函数参数las，它完全完成了任务(感谢作者Andri )。

Answer 2

我不知道在那个包裹里该怎么做。然而，仍然有可能：

tab <- matrix(c(2,5,8,3,10,12,5,7,15), nrow=3, byrow=FALSE)
dimnames(tab) <- list(c("A","B","C"), c("D","E","F"))



PlotCirc( tab,labels = NA, cex.lab = 1.0,acol = c("dodgerblue","seagreen2","limegreen","olivedrab2","goldenrod2","tomato2"),rcol =   SetAlpha(c("red","orange","olivedrab1")))



text(3,15,"ABCDEFG",srt=80)
text(11,10,"BCDEFG",srt=40)
text(13,-5,"CDEFG",srt=-30)
text(-5,-12,"DEFG",srt=60)
text(-12,-5,"EFG",srt=30)
text(-9,11,"FG",srt=-45)
