Hello Steve Thanks for quick responses its really helping me out .Ya I made the necessary changes you had mentioned. I was not sure of that 'type' argument where u had told me to set it to SVM . Do you mean I have to give that argument in this line "cl <- c(c(rep("ALL",10), rep("AML",10)));" and when I ran the code the following output I had got : result: pred ALL AML ALL 7 5 AML 3 5 Does this mean that 7 samples of ALL from test file has been classified as ALL and 5 samples of ALL are classified as AML and so on or is there any other way we can interpret this result . I had done one more thing I had taken the transpose of both my test and train files as given below: model<- svm(t(train),cl); pred <- predict(model,t(test)); And the result I had got is : Result: pred ALL AML ALL 10 0 AML 0 10
why is there a difference in the result which I had given in the before post?does this mean doing transpose classifies the samples better? or is there any reason for this? I am sorry I am troubling you a lot but seriously its a very timely help I am really thankful to you. -Aadhithya -- View this message in context: http://r.789695.n4.nabble.com/Need-help-for-SVM-code-for-microarray-classification-tp2271652p2272658.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.
