Thank you! I have the origenal file in MS-Excel, I save the excel file in a txt file. In the excel file there are missing value empty places for these missing value? 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.
