Repeat if
...e that the Vi is wrong, because in this syntax i is not known as a variable. But I don´t know how to say that it is a variable here. Would be nice if somebody could help me. Perhaps I´m thinking too complicated and there is an easier way to do this.

Count data in random Forest
...statistics beginner) I try to find the most important variables to divide my dataset as given in a categorical variable using randomForest. Is randomForest() able to deal with count data? Or is there no difference because only the ranks are used in the trees?
