Sorry, it's not that I'm trying to make it complicated, but rather specific.
As Gabor said in the earlier post, it seems POSIXlt is not a suitable
argument for read.zoo, and therefore explains the problem that I have been
having. Like I said, I was able to produce the solution that I wanted;
however, it was not as efficient and elegant as I was hoping it to be. When
going through 2 year span data sets, there is a noticeable difference in
speed when you use POSIXlt separately outside the read.zoo function. Anyway,
it's fine. I appreciate the feedback and suggestion. It definitely helps
bounce ideas around and possibly offers ways to expand R source code in the
future maybe. Thanks!
