Dear Nan Qiao,
the accuracies are in percent (so times 100).

Hi:
I am a newer in using R for data mining, and find the "e1071" pakage an
excellent tool in doing data mining work!
what frustrated me recently is that when I using the function "svm" and
using the "cross=10" parameters, I got all the "accuracies" of the model
greater than 1. Isn't that the accuracy should be smaller than 1? so I
wander how, the accuracy of the cross validation is calculated, and
what's the meaning of the accuracy?
