"edit" command does not work as I would expect
Thanks for your email, which was sufficient to point me to my error. Before your email, I had thought that if the file did not exist, then the "edit" command would create the file, since this is what happens when using editor programs under Unix. But in R is not correct, at least on my combination of OS and R. So I first separately created a file called "nam.R" and then tried vi(file="nam.R"). At this point R opened a new window with an editor that controlled the window and enabled one to edit "nam.R", but the editor wasn't vi and it wasn't vim. Maybe it was some standard editor provided with R. My problem is therefore half solved. I cannot see how to invoke a true vim or vi that cooperates directly with R. Do other Mac users experience the same feature? I would be interested to know what happens on non-Mac Unix, Linux or Windows platforms, if anyone can spare the time and has the hardware to try it. Some R-help subscribers seem to regard it as axiomatic that no problem with R on a Mac can occur on other platforms, and I have been strongly re-directed to this list. Now perhaps I'll find out that this particular question is also not appropriate for R-SIG-MAC. Thanks for any help. David

If I had to guess it would be that your file isn't in the working directory. If you supply the entire file location does it work as expected?

I hope I have included all relevant information. I haven't used R for a couple of years. Before restarting with R, I downloaded the latest version I could find in its binary version, and installed it without any problems.
