如何在 R Markdown 中水平绘制决策树?
How to plot a decision tree horizontally in R Markdown?
在 R Markdown 中,我想水平绘制一个决策树,这样它更适合整个 PDF 页面。此代码垂直绘制:
```{r, message=FALSE, warning = FALSE, echo=FALSE, cache = FALSE}
rpart.lrn <- makeLearner("classif.rpart", predict.type = "prob", fix.factors.prediction = FALSE)
model = train(rpart.lrn, task = classif.task, subset = train.set)
tree <- getLearnerModel(model)
rpart.plot(tree) # visualise the tree
```
我怎样才能水平绘制它?
你试过这样设置fig.height和fig.width,例如{r ggpair, echo=FALSE, message = FALSE, warning = FALSE, fig.height = 12, fig.width = 12}
