R help - Oct 2009 - The problem of readLines

Dear R-users,


I use "readLines" to read data, but when processing the large data
set, there are few files which can not be readed in:

48: In readLines(name_c[i]) ... :
  incomplete final line found on 'C:/Documents and Settings/lma/My
Documents/habitdata/244052900243997/calllog/calllog_log-20050505T121611.txt'
...



Whats the problem about this?

Regards,
Tammy

>From the help page for readLines:
" If the final line is incomplete (no final EOL marker) the
     behaviour depends on whether the connection is blocking or not.
     For a non-blocking text-mode connection the incomplete line is
     pushed back, silently.  For all other connections the line will be
     accepted, with a warning. "

You can disable the warning with;

readLines('your_file', warn = FALSE)

I have a more problem: Because there are few files which can't be read into
R completely, so on the following subsequence programme, I use write.table,
which creates the "NA" files for those incomplete files autimatically.
I don't want those NA files. How can I do the following:
whenever readLines can't completely read one file, then autimatically remove
it from my dataset?

Thanks.
Tammy
