I assume that you are using R on some silicon-based electric circuit, but 
that's about all I can guess to understand the error message. In what
command
did it occur? Possibly "read.table"? And try 

  traceback()

after the error message. And if it is during read-in of data, shorten your file 
to 3 lines and try again.

Please do read it carefully.

You have not told us what you are doing, nor provided a reproducible 
example.  Using traceback() will tell you where the error message is 
coming from.

Some searching suggests you are using kmeans().  If you have matrix with 
missing values which you pass to kmeans, this is what you will get.  It 
does not accept missing values, so you will have to decide what to do 
about them.
