Another (similar) question, If I now want to know the name of the "data" argument used, is there an easy way for me to access it?
I'm trying to use something like: eval(parse(text = all.vars(terms(fit1))[1])) Which (of course) wouldn't work, since the response variable is only available in the data used by rpart (specifically the "kyphosis" dataset) Thanks upfront.
