Idgarad,
I guess that all of your factor variables are indicators with levels
"0" and "1". Try changing the levels to "NO", "YES" for one of the
variables and see what you get. I think that the output will clarify
the (actually not) "random" 1s.

Why are my coefficients getting appended with a 1? It borks a match I

added to the end.

Now all the variables with a 1 appended are factors so is that normal
behavior? (if so then I can adjust the match() command to pad a 1 to
the master list.)
