Hi,
I tried to use naivebayes in package 'e1071'.
when I use following parameter, only one predictor, there is an error.
m<- naiveBayes(iris[,1], iris[,5])
table(predict(m, iris[,1]), iris[,5])
Error in log(sapply(attribs, function(v) { :
Non-numeric argument to mathematical function
However, when I use two predictors, there is not error any more.
m<- naiveBayes(iris[,1:2], iris[,5])
table(predict(m, iris[,1:2]), iris[,5])
setosa versicolor virginica
setosa 49 0 0
versicolor 1 37 19
virginica 0 13 31
Do you know what is the problem?
Br,
Luffy
