Re: [R] RandomForest tuning the parameters

Dear Eric thanks for your code, Dear R-experts, Here below my R code, still the same error message at the end while trying to tune the parameters!  Any hints to make it work would be appreciated. Best, # Create features a

Re: [R] RandomForest tuning the parameters

Hi Sacha, On second thought, perhaps this is more the direction that you want ... X2 = cbind(X_train,y_train) colnames(X2)[3] = "y" regr2<-randomForest(y~x1+x2, data=X2,maxnodes=10, ntree=10) regr regr2 #Make prediction predictions= predict(regr, X_test) predictions2= predict(regr2, X_test) HTH,

Re: [R] RandomForest tuning the parameters

Hi, One problem you have is with the command: regr<-randomForest(y~x1+x2, data=X_train, proximity=TRUE) What you need is something like this: X2 <- cbind(X,y) regr<-randomForest(y~x1+x2, data=X2, proximity=TRUE) HTH, Eric On Mon, May 8, 2023 at 11:11 PM varin sacha via R-help wrote: > > Dear

[R] RandomForest tuning the parameters

Dear R-experts, Here below a toy example with some error messages, especially at the end of the code (Tuning the parameters). Your help to correct my R code would be highly appreciated. ### #libraries library(lattice) library(ggplot2) library(caret) library(
