Dear R-users, While making a prediction using the randomForest function (package randomForest) I'm getting the following error message:
"Error in predict.randomForest(model, newdata = CV) : No forest component in the object" Here's my complete code. For reproducing this task, please find my 2 data sets attached ( http://www.nabble.com/file/p17855119/data.rar data.rar ). Thanks in advance for any help! - Jim CT <- read.table("CT.txt",header=TRUE,sep="\t") CV <- read.table("CV.txt",header=TRUE,sep="\t") # Both CT & CV have the syntaxis X1, X2,...,X97,Y where all variables are numeric x <- CT[,-98] y <- CT[,98] xtest <- CV[,-98] ytest <- CV[,98] library(randomForest) model <- randomForest(x ,y , xtest, ytest,ntree=500,mtry=32,nodesize=5,nPerm=2) model #Call: # randomForest(x = x, y = y, xtest = xtest, ytest = ytest, ntree = 500, mtry = 32, nodesize = 5, # nPerm = 2) # Type of random forest: regression # Number of trees: 500 #No. of variables tried at each split: 32 # # Mean of squared residuals: 0.0022117 # % Var explained: -1.01 # Test set MSE: 0 # % Var explained: 2.61 prediction <- predict(model, newdata= CT) #Error in predict.randomForest(model, newdata = CV) : # No forest component in the object # -- View this message in context: http://www.nabble.com/randomForest%2C-%27No-forest-component...%27-error-while-calling-Predict%28%29-tp17855119p17855119.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
