Я создаю дерево решений в R, которое имеет около 50 категориальных и непрерывных переменных. Я хотел бы отобразить дерево решений, которое я создаю с использованием Rpart, в лучшем формате, чтобы отображалось только имя переменной, а не имя переменной и все уровни фактора. Если вы посмотрите на выходные данные ниже, имя первого узла даже не помещается на странице, я хотел бы, чтобы оно показывало только короткое имя, соответствующее имени переменной.
Это разные способы, которыми я пытался отобразить дерево решений:
temp_dia<- read.csv("~/temp_dia.csv")
fit<- rpart(temp_dia$diabetesMed ~ ., method = "class", data = temp_dia, control = rpart.control(minsplit = 10, cp = 1e-04), parms = list(prior = c(0.3, 0.7)))
#1
rpart.plot(fit, type = 2)
labels(fit,minlength=2)
#2
plot(cart_fit, uniform = TRUE, main = "Diabetes Tree: CART Method")
text(cart_fit, cex = .5, pretty = 1)
#3
fancyRpartPlot(cart_fit, tweak = 1, cex = .4)
И выходные данные всегда различаются по-разному:
