I have a question regarding NA in randomForest (in R). I have a dataset
which include both numerical and non-numerical variables, and the data
includes some NA. I tried to use na.roughfix but then i get an error
message "na.roughfix only works for numeric or factor". I also tried
rfImpute but this does not work either because I have some NA in my
response variable. Does anyone have som tips to how I can deal with this?
