Is that a complete representation of your console? It doesn't look
syntactically valid R as it came across to my mail-client, and it
produces a different error message when pasted into my console.
Shouldn't there be an operator after "inkm " (perhaps ";" if you
wanted to see "inkm" before doing work on it)? And what is "inkm"? You
are asked to offer reproducible examples. Did you want to assign the
result of drop1() to glm.incm. If so, a "<-" would be needed, and I
at least don't see one.
So either your mail-client is not transmitting punctuation the same
way some ((most?) of us are used to seeing it, or you have come from a
programming world that is quite different than R.
