Please help! Error with RandomForest using the diabetics dataset.

Code -

Error -
Error in y - ymean : non-numeric argument to binary operator
In addition: Warning messages:
1: In randomForest.default(m, y, ...) :
  The response has five or fewer unique values.  Are you sure you want to do regression?
2: In mean.default(y) : argument is not numeric or logical: returning NA

Answer 1

Hey,

Convert the Class.variable to factor then it might work.

random_forest = randomForest(as.factor(Class.variable)~.,data = train,ntree = 10,importance = T)
