I do not understand what you are calling “the table”. Did you use attach() on a dataframe that has those variable names as its column names? Using `attach` is very unwise, often leading to getting puzzling error messages. If my guess is correct, you should detach() the dataframe and post the output of summary( <whatever name it might have>). It appears you do not understand what is in the `V12` column.
