I am new to R and start to play around naive bayes algorithm. But I run into a
problem which I could not figure out why: for the following sample data, the
predict function (using a naive bayes model) always gives me zero length. Do
you have any hints? Thanks
Here is the code:
> titanic_small
survived pclass
1 0 3
2 1 1
3 1 3
4 1 1
5 0 3
6 0 3
> model <- naiveBayes(survived~., data=titanic_small)
> prediction <- predict(model, titanic_small[,-1])
> length(prediction)
[1] 0
