Example of use of "random jungle" in 'R'

Question

I'm trying to build an rjungle model based on an example, but I'm getting an error when I try to use the model for a prediction.

Here is where I got the package:

• https://github.com/jkruppa/Rjungle

Install code:

library(devtools)
install_github("Rjungle", username = "jkruppa")

Here's my code to try and run it against iris data:

#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

What I got:

Though it is very simple code, it should work according to the help doc. Instead I get this, which I don't know how to understand.

Warning message:

There is something in "est" so I try to "predict" using it, and get the following error:

Error in file(file, "r") : cannot open the connection
