[R] SVM Prediction and Plot

Hi
I'm trying to predict using a model I fitted with SVM.
I constructed the model (called Svm) using a training set, and now I want to
use a test set (called BankTest) for prediction.
The response variable is in the first column of BankTest.
> SvmPred = predict(Svm, BankTest[,-1], probability=TRUE)
> SvmPredRes = table(Pred = SvmPred, True = BankTest[,1])
I get this error:
Error in table(Pred = SvmPred, True = BankTest) : all arguments must have
the same length
I checked the length of both BankTest[,1] and SvmPredict.
> length(SvmPred)
[1] 2282
> length(BankTest[,1])
[1] 2598
How are these two columns not the same size? Surely the prediction should
try to predict all the values of BankTest[,1]?
Any help would be much appreciated.
