Capitalization is important in R, so when asking a question, please cut 
and paste what you actually did.  In this case, it doesn't matter.

Those are warnings, not errors.   readLines gives those warnings when 
the last line of the file stops abruptly, rather than having an end of 
line marker.  On Unix systems this usually signals a problem with the 
file.  Windows is more tolerant, so many editors don't bother to add the 
final marker.

I think you need to convert them to text first (by some tool outside of 
R), but I might be wrong.
