Help in SVM prediction
...10 10 17 17 33 6 ...
$ X1 : num 29105 29105 29105 29105 29105 ..
I want the prediction of X consolidated on the basis of X4 into a separate
data frame. The loop that I wrote for this is:
len<-nrow(test);
prediction<-data.frame(t(rep(NA,2)));
names(prediction)<-c("X4","PredictionX");
prediction<-prediction[-1,];
for(j in 1:len)
{
prediction[j,1]<-test[j,1];
Forecast.List[j,2]<-predict(X,test[j,]);
}
when I do this I get the following error: Error in `contrasts<-`(`*tmp*`,
value = "contr.treatment") :
contrasts can be applied only to factors...
