Hi,
Could you please tell me how I correct the following error message?
“Error in object$tables[[v]] : subscript out of bounds”
This is the code:
library(e1071)
data(iris)
attach(iris)
class_label<- names(iris)[1]
This is not the name for the class variable of the wiris data from R.
myformula<- formula(paste(class_label,"~ ."))
Why do you construct this in a so complicated manner rather than typing
the formula directly?
mymodel<-naiveBayes(myformula, iris,cross=3)
naiveBayes sort of fails (well, it runs smoothly but the result won't
make sense) here since it expects a class variable.
predict(mymodel,iris) ##Error in object$tables[[v]] : subscript out of
bounds
Works for me.
Please upgrade R, e1071 and run in a clean session to see that the code
above does not fail. Although it makes absolutely no sense.
Uwe Ligges
Cheers,
Amy
