Need small help. I have some hundred samples and I have already classified them into four different classes (clusters). Now, I'm interested in identifying the best set of genes that classify the samples into different classes. Both up and down genes in each class.
For this I have already used t-test. But I'm interested in applying random forest for selecting features. My data looks like below. Just posting some example data here.
Can anyone please tell me how I can use the above data and apply random forest to know which genes classify the samples into different classes. thanq.
