Josh, Unfortunately, I created a lot of lines after getting it working, so there was no getting back to it, and right now I can't reproduce it - sorry. If I use one Gnome shell and exit R and re-run it, am I clearing everything? I assume so, but if not, that might be relevant. AFAIK, I do not save and re-use workspaces.

I am sure this has already taken enough of your time, and since its working for you now, I would not worry about looking into it further. I know that I have seen something in the past that produced a short output about an object exactly like what you described (data frame with n rows and m columns), but I cannot remember what it was for the life of me.
