我正在尝试基于一个示例构建一个rjungle模型，但是当我尝试使用该模型进行预测时，我遇到了错误。
这是我收到包裹的地方：
安装代码：
library(devtools)
install_github("Rjungle", username = "jkruppa")
这是我的代码，尝试针对虹膜数据运行它：
#get data
data(iris)
#prove data is in workspace
plot(iris)
#try to make jungle (warning comes from this, but not error)
est <- rjungle(depVarName = "Species",
data=iris,
ntree=200,verbose = T)
#something comes out
summary(est)
mypred <- predict(object = est,data = iris) # ERROR is here
我得到了什么：
虽然代码非常简单，但它应该根据帮助文档工作。相反，我得到了这个，我不知道该怎么理解。

“est”中有一些东西，所以我尝试“预测”使用它，并得到以下错误：
