I ran Random Forest Model in R then now i call it to predict my dataset

predict.rf<-predict(layers.stack,random.forest, na.rm=T, type='response')

However it comes with one error as follow:

Error in UseMethod("predict") : no applicable method for 'predict' applied to an object of class "c('randomForest.formula', 'randomForest')"

Do anyone know how to fix this error pls?

Regards

The problem can only be solved with access to a sample of your data. – NelsonGon
dear NelsonGon, thank you very much for your comment, i know it is hard for you to solve problems without data set however out dataset contains 88 satellite images which is over 200 GB so I could not upload the one here, very sorry for that – tnbang

It appears that you are using two different R scripts - one for training, and another one for prediction. This error means that your prediction R script does not know about the randomForest(.formula) class.

You can fix it by simply importing the "randomForest" library into your prediction R script:

library("randomForest")
