Hi, I have some difficulties in interpreting the prediction of a svm model
using the package e1071.

y1 is the variable I want to predict. It is of type factor and has got two
levels:  "< 50%" and "> 50%".
z is the dataset.

> model <- svm(y1 ~ ., data = z,type="C-classification", cross=10)
> model

Call:
svm(formula = y1 ~ ., data = z, type = "C-classification", cross = 10)


Parameters:
   SVM-Type:  C-classification
 SVM-Kernel:  radial
       cost:  1
      gamma:  0.07142857

Number of Support Vectors:  68

> pred <- predict(model,newdata=z,probability=TRUE,decision.values = TRUE)
> table(pred)
pred
< 50% > 50%
  414     0

The results of "pred" is not what I intended to get as, I expected this
type of result:

           < 50% > 50%

 < 50%    89        25
> 50%     38        262

What should I do?
