Use other kind of object different to continuous, or categorical #69

Open Afr063426 opened 1 day ago

Afr063426 commented 1 day ago

Hello, I am trying to use my own metric to define splits. The y variable is no continuous neither categorical. It is an object created, and it is a list with two vectors with vctrs::new_vctr. I get this error "Error in model.frame.default(formula = histograma ~ prueba, data = histogramas_ejemplo : invalid type (list) for variable 'histograma'" Someone have tried something similar? And how do you solve this?

The function is designed to use results from model.matrix(). Does the endpoint that you've created work with model.matrix?

No, should I do that work with model.matrix? And with this should it work?

Start by getting model.matrix to work
