Hi Brodie, Thanks for your suggestions, I definitely appreciate it.
Yes, I realize these aren’t Mac-specific questions, so forgive a new member the mistake of accidentally posting to the wrong listserv. I realized that after the fact, but there it is. I think I discovered two problems today that I got worked out. The first was a permissions problem that is macOS-specific: I installed XQuartz, and inside my xterms, I was unable even execute simple commands such as ‘ls’. Google to the rescue. After that, I got the permissions sorted out, and those commands worked just fine. I suspect because I couldn’t even do things like that, that that’s why I was getting (IIRC) “Operation not permitted” errors *inside of R* trying to open a file. Being new to it, it appeared to me that R was the cause of my problem. Once I got that sorted out, it was no issue. The second problem was figuring out which file operation method to use. file.choose() worked for me, and it was quite easy to wrap this with a read.table(), so that was a nice bit of learning. (The CLI did not permit me to do anything other than type in a fully-qualified path to my data files, but in R.app, it nicely opened up a file selection dialog, about which I was very pleased.) One of the reasons I didn’t initially provide a lot of supplementary information was that I figured if anyone had any suggestions based on what the problem sounded like, they might have vectored me in the right direction. Typically I provide a lot of detail up front but that ends up getting lost on people, so I’ve learned to start general and then if they’re willing to be helpful, I’ll gladly supply the info. I hadn’t thought of Stack Overflow, but based on the initial reax here, I started Googling other sites that might provide more useful examples without the backtalk. Thirty years on the Internet and some things never change. ;) Thank you again!

Do you have reason to think this is a Mac specific issue? If not this is likely not the right mailing list. Perhaps r-help might be better, although I do think you will find more people willing to pitch in on Stackoverflow (but avoid cross-posting, so since you have already posted here you might need to hope someone is willing to provide you an answer). 2. The reason you are getting the reactions you are in this thread (apart from the mac-specific issue) is that there is not enough information for others to debug your problems. E.g. what does the file look like, in what way does it "definitely not work"?. Do you get an error? Or do you import something that doesn't look like what you expected? These are all things that are needed by anyone that will want to help you, and it frustrates some that you are not providing them of your own initiative. If I were in your shoes I would try my luck on stackoverflow, or alternatively, read through several threads on R-help to figure out how the Q/A process works there and ask questions in ways that are likely to elicit answers. This is not easy to do and take some work to figure out, but when asking for folks time to help you it is a good idea to try to do some home work ahead of time. I speak only for myself, and sincerely hope this non-answer is helpful to you even if it doesn't actually address your questions. Best, Brodie.
