I think the command you want is:
if(t %in% feed_days) C_A - 1.5 else C_A - 0
Do not confuse `%in%` (which is essentially
are the left-hand values in the right-hand
vector)
with
in of the `for` loop.
By the way,
if(t == TRUE)
is redundant -- better is:
if(t)

I forgot to say:
Also do not depend on equality in this situation.
You want to test equality with a tolerance.

I also see that 't' is a vector unlike what I was
thinking before, thus you want to use
