A 'closure' is a function and you cannot use '[' or '[[' to make a
subset of a function.
You used
forecast[d+1] <- ...
in one branch of the 'if' statement and
forecasts[d+1] <- ...
in the other. Do you see the problem now?
By the way, the code snippet in the error message says '[[d+1]]' but
the code you supplied has '[d+1]'. Does the html mangling selectively
double brackets or did you not show us the code that generated that
message?
