[R] plot of a bagging tree

[Massimo Bressan]

by considering this general example

##start code

library(ipred)
data("Ionosphere", package = "mlbench")
Ionosphere$V2 <- NULL # constant within groups
iono<-bagging(Class ~ ., data=Ionosphere, coob=TRUE)
print(iono)

##end code

does anybody knows any possibility to plot the (average) plot of the 
bagging?
does it make any sense at least for a visual presentation?
how to *visually* convey the information provided by the bagging model?

thank you for any feedback

best
