R help - Nov 2003 - How to represent pure linefeeds chr(10) under R for Windows

I need to write out with write.table() a csv file allowing for line feeds
(pure chr(10)) as part of character field (not as a line seperator).

How can I do that?

Best regards

Use \n in the character string, if I understand you aright, as in

foo <-"a\nb"

Brian, Simon,

Thanks for your quick answers. Unfortunately neither \n nor \012 works.
Under R for Windows (tried on 1.8.0 and 1.5.1) they are automatically converted
to chr(13)+chr(10).

I need only chr(10) within my string column, and chr(13)+chr(10) at line
ends of the csv file. If it can't be solved within R, I could workaround by
substituting all chr(13)+chr(10) into chr(10) after writing the file using a
system() call. However, writing the files twice would be ugly and performance
reducing (I am writing an interface).

Any idea?

Best regards

You may have to write as a binary file to get this to work. I would try
opening a binary file connection and passing it to write.csv, but that
might mess up the real line endings.
