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.

Bill

I mostly meant look at whatever past commands you had typed using the "up" 
arrow (only useful for a very limited number).  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.
