Hello, can me please help anbody how it is possible unlist a "rpart.object.list" i.e. from bagging(ipred) to plot this "unique" several rpart.objects . ..i make attempts with unlist, get really atomic elements, but need only the different tree's !
Right, that's what unlist() does. In ?bagging (package ipred), you will find in section "Value": Value An object of class bagging: a list containing the following objects mt list of length nbagg containing rpart trees. So, following the first example in ?bagging, you get a list of trees with: X <- as.data.frame(matrix(rnorm(1000), ncol=10)) y <- factor(ifelse(apply(X, 1, mean) > 0, 1, 0)) learn <- cbind(y, X) mt <- bagging(y ~., data=learn, coob=TRUE) mt$mt Uwe Ligges -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
