[R] Fatigued R

[Sarah Goslee]

That's a help. It isn't actually reproducible since I have no idea where
for example blpConnect() comes from, but it's still an improvement.

Moving the important bit to the top:

These seem to mean that your data don't (always?) look like you are
expecting, and have nothing to do with fatigue or sleepiness. Except
maybe yours?

I would suggest going through your function one command at a time
(without the loop, but set the loop index manually if needed), and check
carefully the format of the data. If it works sometimes and not others,
identify a loop index for which it doesn't work and repeat the process.

Someone familiar with Bloomberg data might be able to provide more
assistance.
