for example,use the dataset Vanveer.4000 in library(MASS), 1.if i used the first 300 genes, how to find the single trees and random forests by using R? And how to see their classification performance? 2.how to compute the error rate by using 10-fold cross validation? and how to produce a ROC curve? 3.how to find the numbers of "good" outcome are misclassified? Thank you very much for your help. -- View this message in context: http://n4.nabble.com/About-Random-Forests-ROC-Misclassified-tp2014981p2014981.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
