[R] R Error

[john.hogan]

Hi,

I am having a small problem with my code that is preventing my source file
from running. Can anyone identify my error and how to maybe resolve the
issue? 

command when error occurs:
modelprobability_genderNB <- naiveBayes(gender ~ ., data =
probability_genderNB)

My error:
Error in tapply(var, y, mean, na.rm = TRUE) : 
  arguments must have same length

My dataset: 
gender    relationship
Male	   1
Male	   1
Female	  1
Female	  2
Male	   1
Male	   1
Female	  2
Female	  1
Male	   2
Male	   1
Female	  1
Male	   2
Female	  1
Male	   1
Female	  1
Male	   1
Male	   2
Female	  2
Male	   2
Male	   1
Male	   1
Female	  1
Female	  2

Hope to hear from someone soon.

Regards,

John.
