Hey!
How do I get the confusion matrix after performing 10-fold cross validation
from SVM in R?
When I try to print it, I get the confusion matrix without cross validation.
I need to compute PPV. Should I report PPV without CV and total accuracy
with CV?
I am confused.
> svmtrain <- svm(xtrain,ytrain,kernel="sigmoid",cross=10)
> pred <- predict(svmtrain, xtrain)
> table(pred, ytrain)
