How can I set the number of attributes to be selected using cfssubseteval?

[lebebop]

I'm trying to use cfssubseteval with BestFirst. I want to select N attributes based on correlation.
Do you guys have any sugestion?

You can't do that with the BestFirst search, but you can with GreedyStepwise by turning on the option to produce a ranked list and then setting the number of attributes to select. Alternatively, you can use the CorrelationAttributeEval with the Ranker search method.
