Hello, I need to classify (i.e., export a vector with terminal node id's) new cases using a ctree (party package) model based on different cases (learning sample).
I tried the where command with the following syntax: > where(tree, newdata=data2) expecting to get terminal nodes of data2 cases based on rules of tree model (data1 as learning sample). However it returned the following error message: Error in checkData(oldData, RET) : Classes of new data do not match original data Party documentation states that I can use this command both for learning sample (newdata=NULL) or new observations. What am I doing wrong?
