我想绘制一个 ID3 模型的结果。它似乎在 WEKA 和 R 中都没有默认的绘图模块。
是否有已经制作的代码来执行此操作？（或者，下面的树格式是否有一个标准名称，我可以很容易地找到一个解析器？）
这是一些基本代码：
# I'm getting a post from this: https://en.wikipedia.org/wiki/ID3_algorithm
## load RWeka
if(!require(RWeka)) install.packages("RWeka")
library(RWeka)
## look for a package providing id3
WPM("refresh-cache")
WPM("list-packages", "available") ## look for id3
## install package providing id3
WPM("install-package", "simpleEducationalLearningSchemes")
## load the package
WPM("load-package", "simpleEducationalLearningSchemes")
## make classifier
ID3 <- make_Weka_classifier("weka/classifiers/trees/Id3")
## test it out.
DF2 <- read.arff(system.file("arff", "contact-lenses.arff",
package = "RWeka"))
ID3(`contact-lenses` ~ ., data = DF2)
结果如下：
Id3
tear-prod-rate = reduced: none
tear-prod-rate = normal
| astigmatism = no
| | age = young: soft
| | age = pre-presbyopic: soft
| | age = presbyopic
| | | spectacle-prescrip = myope: none
| | | spectacle-prescrip = hypermetrope: soft
| astigmatism = yes
| | spectacle-prescrip = myope: hard
| | spectacle-prescrip = hypermetrope
| | | age = young: hard
| | | age = pre-presbyopic: none
| | | age = presbyopic: none
树形结构很容易理解。关于如何解析这个有什么建议吗？（也许类似于这里的答案？）
谢谢。
