r - All arguments must be the same length using svm -

i trying apply svm on data in order predict future data. have faced following error:

all arguments must same length  > svmmodele1<-svm(data$note ~ appcache+tcp+dns,data=data,scale = false,kernel="linear",cost= 0.08,gamma=0.06) > svm.video.pred1<-predict(svmmodele1,data) > svm.video.pred1  1  3  4  5  6  7 10 11 12 13 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31   3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54   3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  3  levels: 1 2 3 4 5 > svm.video.table1<-table(pred=svm.video.pred1, true= data$note) error in table(pred = svm.video.pred1, true = data$note) :    arguments must same length   data$note  [1] 2 2 2 3 3 3 2 2 2 1 1 1 1 1 1 3 3 3 3 3 3 3 3 3 4 4 4 3 3 3 4 4 4 4 4 4 5 5 [39] 5 5 5 5 5 5 5 3 3 3 1 1 1 1 1 1 levels: 1 2 3 4 5 

for stuck on same problem, reason of error have negative variable.
