Hi! I have a questionaccording to classifing new examples from an already trained svm. I have tarined a svm (e1071 package) with a training set of 1526 examples. Now I have another data set with 2163 examples and I want to use the already trained svm for prediction: pred<-predict(a.svm,newdata); Afterwards for further processessing I add further information to the results of teh classification from the original input (also 2163 x N matrix) result<-as.data.frame(cbind(newdata[81:84],pred)) But I receive an error: Error in data.frame(..., check.names = FALSE) : arguments imply differing number of rows: 2163, 1526 So I wonder why the svm is stick to a resultset of 1526 although I put in 2613 examples? To my mind I thought that the classification/predictin depends on the length of the feature vector not on the number of examples? Or am I doing something wrong? Thanks -- Frank G.
