[R] Question about Line Ending Choice

eol seems to be the parameter to use, but the answers so far appear to assume that the file is created on a Mac. For example, I think that �\r\n� on Windows would produce CR CR LF. I don�t have both systems handy (so I can�t test), but I think you should use raw to specify the bytes you want.

# I think the following are independent of the OS on which you are writing the file.
CR <- rawToChar(as.raw(13))
LF <- rawToChar(as.raw(10))
if missing(target)
  # Hope that it matches the machine on which you are writing the file.
  eol <- �\n�
else if (target==�Windows�)
  eol <- c(CR,LF)
else if (target %in% c(�Unix�,�Mac�))
  eol <- LF
else if �.
  stop(�Unexpected target.�)

write.table(eol=eol, �.)

Hi Bert,

Thanks for the reply.

I did see the parameter, but was not sure if this is the correct
parameter to reference. I also see it in write.csv.

I take it you are saying the eol parameter is the best practice for
exporting from R using these functions. Am I correct or is there another
option other than write.csv and write.table I should be considering?
