In the absence of any of your code, there is not much we can do, except to
comment that if() (of your subject line) only knows about TRUE and FALSE,
so we can only guess at what you used to test equality.

No code arrived here. What `attached (and not included' means is unclear
to me, but only the dataset arrived.
