[R] problems in cross validation of SVM in pakage "e1071"

Dear Nan Qiao,

the accuracies are in percent (so times 100).




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?
