Do I need to replace the empty places in a symbol for missing value and could you tell me place how can I avoid this warning message?

Thank you in advance!

R is warning you that the file may be incomplete. In Unix, text files 
are supposed to always end with a newline.  Windows programs often omit 
it on the last line.  So on Unix, R is probably right to warn you, but 
it could well be a false positive if you're on Windows.

How you deal with missing values really depends on what you want to do 
with the data.  There's no general answer.
