I am having the same problem (#3) with read.table on Darwin. The edit() function is not a work-around for me since I have to read an enormous text file. I tried copying the data from TextEdit and pasting it into vi and Project Builder, but that didn't help at all. I wonder if this is related to the MacOS convention of ending lines with "\l" instead of "\n".
It's CR (ctrl-J, \r) as far as I know. Shouldn't be a problem. R's input handles all the standard line-ending conventions (LF, CRLF, CR) on all platforms, and this is tested as part of the test suite (although I don't know if that is run on MacOS).
The strange thing is that read.delim() seems to work fine.
and that calls read.table, so the problem is either with the separators or more likely with surplus separators at the end of lines in some lines. You can use a dump (use od under Unix) to find out what is really in the file. Neither of you have anywhere told us what the actual error message was in problem number 3.

Thanks to all who responded. Not all of the advice helped me with that particular problem, but, I have learned a lot just from your answers. 1. R for Mac 10 (Carbon version) uses the Mac convention of using ":" for the usual Unix "/" and thanks to Dr. Lumley for that since I'm new to R, Mac10, Macs in general, and Unix. 2. Interestingly, Dr. Ripley suggested to me not to use spaces in the path as R wouldn't be able to read them.
y(That's not what I said. The posting by the time it reached me had a surplus newline and space in the file spec, at the end of a path component. R does handle legal file names including spaces. My comment as on the file spec as received, not in general.) [...]
