Hello there: I got 13 variables in my training/target set, the first 12 variables are mixture of numerical and categorical variables. The last one is the one I need to predict, and it is a numerical variable.
>train<-read.table("train.txt") >test<-read.table("test.txt") >cl<-factor(train[,13]) >pred<-knn(train, test, clk=3, prob=TRUE) >pred I got output on the screen as following 8.10832229 8.831127635 7.592870288 8.521782644 6.376726948 6.914730893 9.71534911 8.658171785 6.104793232 7.247080585 6.298949247 5.105945474 7.508238775 7.65396918 8.831127635 7.912056888 6.381816017 7.211556733 276 levels ............ Then I tried to calculate a formula:(actual-pred)/actual, which includes pred values. However, I cannot do this even I convert the factors in pred to vectors. Can anybody help?? Thank you very much indeed, Qin ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
