How to use factors (such as age) as covariates in Classifier app (machine learning)?

Hi,

I have a question about using Age and other factors as covariates in Classifier app (Machine Learning).

I am able to classify my data using Classifier app (Machine Learning). My data is of the dimension 60x34 - where 60 is my training sample size (with 2 groups of size 32 and 28, randomized) and 34 is my # of data points. I want to include the age and gender of these 60 subjects (training sample size) as covariates in this classification. But I am not able to find any instructions in the description of Classifier app explaing how to include covariates in the process?

Any help would be really appreciated.

Thanks !
