有没有办法改变 ctree 图的标题大小?

Is there any way to change the title sizes of a ctree plot?

使用以下变量快速设置ctree图

Use the following variables to quickly set up a ctree plot

a<-c(41, 45, 50, 50, 38, 42, 50, 43, 37, 22, 42, 48, 47, 48, 50, 47, 41, 50, 45, 45, 39, 45, 46, 48, 50, 47, 50, 21, 48, 50, 48, 48, 48, 46, 36, 38, 50, 39, 44, 44, 50, 49, 40, 48, 48, 45, 39, 40, 44, 39, 40, 44, 42, 39, 49, 50, 50, 48, 48, 47, 48, 47, 44, 41, 50, 47, 50, 41, 50, 44, 47, 50, 24, 40, 43, 37, 44, 32, 43, 42, 44, 38, 42, 45, 50, 47, 46, 43,
37, 47, 37, 45, 41, 50, 42, 32, 43, 48, 45, 45, 28, 44,38, 41, 45, 48, 48, 47 ,49, 16, 45, 50, 47, 50, 43, 49, 50)

X1<-c(NA,NA,NA,NA,NA,1,2,2,2,NA,2,2,2,2,2,2,2,NA,NA,2,2,2,2,NA,2,2,2,2,2,2,2,NA,NA,NA,NA,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,NA,2,2,2,2,2,2,2,2,2,2,NA,2,2,2,2,2,2,2,2,2,2,2,1,2,2,2,2,2,1,2,2,2,2,2,1,1,2,2,2,2,2,2,2,2,2,2,2,2,2,1,1,2,2,1,2,2,2)
X2<-c(NA,NA,NA,NA,NA,NA,2,2,2,NA,NA,2,2,2,2,2,2,NA,2,2,2,2,2,NA,2,2,2,2,2,2,2,NA,NA,NA,NA,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,NA,2,2,2,2,2,2,2,2,2,2,2,1,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,1,2,2,2,2,2,2,1,2,2,2,2,2,2,2)
X3<-c(NA,35,40,NA,10,NA,31,NA,14,NA,NA,15,17,NA,NA,16,10,15,14,39,17,35,14,14,22,10,15,0,34,23,13,35,32,2,14,10,14,10,10,10,40,10,13,13,10,10,10,13,13,25,10,35,NA,13,NA,10,40,0,0,20,40,10,14,40,10,10,10,10,13,10,8,NA,NA,14,NA,10,28,10,10,15,15,16,10,10,35,16,NA,NA,NA,NA,30,19,14,30,10,10,8,10,21,10,10,35,15,34,10,39,NA,10,10,6,16,10,10,10,10,34,10)
X4<-c(NA,NA,511,NA,NA,NA,NA,NA,849,NA,NA,NA,NA,1324,1181,832,1005,166,204,1253,529,317,294,NA,514,801,534,1319,272,315,572,96,666,236,842,980,290,843,904,528,27,366,540,560,659,107,63,20,1184,1052,214,46,139,310,872,891,651,687,434,1115,1289,455,764,938,1188,105,757,719,1236,982,710,NA,NA,632,NA,546,747,941,1257,99,133,61,249,NA,NA,1080,NA,645,19,107,486,1198,276,777,738,1073,539,1096,686,505,104,5,55,553,1023,1333,NA,NA,969,691,1227,1059,358,991,1019,NA,1216)

p<-cbind(X1,X2,X3,X4)

有了以下内容，您应该得到下面的情节

With the following you should then get the plot below

library(party)  
urp<-ctree(a~., data=data.frame(a,p))
plot(urp, main = "Broken Title")

如何更改标题大小?我试过以下什么都不做:

How do I change the title size? I've tried the following which does nothing:

plot(urp, main = "Broken Title",cex = 1.5)
plot(urp, main = "Broken Title",cex.main = 1.5)

事实上，我可以操纵标题吗?font.main 同样什么都不做.节点 2"和节点 3"这两个标题怎么样?难道我也没有办法操纵它们吗?

In fact, can I manipulate the title at all? font.main similarly does nothing. What about the titles "Node 2" and "Node 3." Is there likewise no way for me to manipulate them?

这里有人问过类似的问题:https://stackoverflow.com/questions/18817522/ctree-changed-titles-of-内部节点

A similar question was asked here: https://stackoverflow.com/questions/18817522/ctree-changing-titles-of-inner-nodes

推荐答案

有好消息也有坏消息.

所以 plot() 函数实际上完成了那里的所有工作，就是 party::plot.BinaryTree.?plot.BinaryTree 提供了帮助，但坏消息是它没有任何易于访问的字体格式参数.不过，好消息是该函数使用网格图形绘制到屏幕上，您可以在创建绘图后更新属性.

So the plot() function that's actually doing all the work there is party:::plot.BinaryTree. The help is available from ?plot.BinaryTree but the bad news is it doesn't have any easily accessible parameters for font formatting. However, the good news is that the function uses grid graphics to draw to the screen and you can update properties after you've created the plot.

所以在你跑完之后

library(party)  
urp<-ctree(a~., data=data.frame(a,p))
plot(urp, main = "Broken Title")

你可以运行

for(gg in grid.ls(print=F)[[1]]) {
   if (grepl("text", gg)) {
       print(paste(gg, grid.get(gg)$label,sep=": "))
   }
}

查看绘图上的所有文本框.例如，我看到

to see all the text boxes on the plot. For example, I see

[1] "GRID.text.673: Broken Title"
[1] "GRID.text.677: X1"
[1] "GRID.text.678: p = 0.03"
[1] "GRID.text.680: 1"
[1] "GRID.text.682: phantom(0) <= 1"
[1] "GRID.text.684: phantom(0) > 1"
[1] "GRID.text.686: Node 2 (n = 8)"
[1] "GRID.text.697: Node 3 (n = 109)"

在这里我看到节点名称，以及它们包含的文本.请注意，节点名称因绘图而异，并更改绘制相同绘图的所有内容.但是您可以使用此列表来查找要更改和更新的列表.所以如果我想让正文更大，我会运行

Here i see the node names, and the text they contain. Note that the node names are not the same from plot to plot and change everything you draw the same plot. But you can use this list to find the ones you want to change and update them. So if I wanted to make the main text bigger, I would run

grid.edit("GRID.text.673", gp=gpar(fontsize=20))

或者如果我想将节点标签斜体，我会运行

or If i wanted to italize the node labels i would run

grid.edit("GRID.text.686", gp=gpar(fontface=3))
grid.edit("GRID.text.697", gp=gpar(fontface=3))

这就给了
