I am getting an error while running naive bayes classifier in R. I am using the following code-
mod1 <- naiveBayes(factor(X20) ~ factor(X1) + factor(X2) +factor(X3) +factor(X4)+factor(X5)+factor(X6)+factor(X7)
+factor(X8)+factor(X9)
+factor(X10)+factor(X11)+ factor(X12)+factor(X13)+factor(X14)
+factor(X15)
+factor(X16)+factor(X17)
+factor(X18)+factor(X19),data=intent.test)
res1 <- predict(mod1)$posterior
First part of this code runs fine. But when it try to predict the posterior probability it throws following error-
**Error in as.data.frame(newdata) :
argument "newdata" is missing, with no default**
I tried running something like
res1 <- predict(mod1,new_data=intent.test)$posterior
but this also gives the same error.
