[R] cat(), Rgui, and support for carriage return \r...

[Christos Hatzis]

I think you meant

.Platform$OS.type == "windows"

Wouldn't be useful to add an "eol" element to the .Platform list storing the
os-specific eol character as was done with the "file.sep" character.

You could try this:

eol <- if (Platform$OS.type == "windows") "\n" else "\r"

and then use the eol variable in your cat statement.
