End of line marker?

Thank you so much for your reply.



I can identify the characters very easily in a couple of files. The reason I
am worried is that I have thousands of files to read in. The files were
produced in a very old MS-DOS software that records information on
oceanographic data and geographic position during a survey.



My main goal is read all these files into R for further analysis. Most of
the files are cleared of these EOL markers but some are not. I only noticed
the problem by chance when I was looking and comparing one of them. I wonder
if I can solve this problem using R, without having to go for text editors
separately.



Help on this would be much appreciated.

Thanks again



J

Dear R users,

I am trying to read a huge file in R. For some reason, only a part of the
file is read. When I further investigated, I found that in one of my
non-numeric columns, there is one odd character responsible for this,
which
I reproduce bellow:
In case you cannot see it, it looks like a right arrow, but it is not the
one you get from microsoft word in menu "insert symbol".

I think my dat file is broken and that funny character is an EOL marker
that
makes R not read the rest of the file. I am sure the character is there by
chance but I fear that it might be present in some other big files I have
to
work with as well. So, is there any clever way to remove this inconvenient
character in R avoiding having to edit the file in notepad and remove it
manually?

Code I am using:

read.csv("new3.dat", header=F)

Warning message:
In read.table(file = file, header = header, sep = sep, quote = quote, ?:
?incomplete final line found by readTableHeader on 'new3.dat'

I think you should identify the offending line by using the count.fields
function and fix it with an editor.
