Easy question a bit. So here's my code:

I am trying to read in a series of timestamps. However with POSIXlt as
FUN in read.zoo, the output is merely two numbers and is not the output
that I'm hoping for. The code above should reproduce the error.
You just need to declare that the index is in two columns (1 and 2) and
then provide a function that extracts a suitable object from it:
read.zoo("test.txt", header = FALSE, index = 1:2,
FUN = function(x, y) strptime(paste(x, y), "%d/%m/%Y %H:%M"))
Use an additional as.POSIXct(...) around the strptime() call if you want
to use POSIXct instead of POSIXlt which is typically recommended.
See vignette("zoo-read", package = "zoo") for more examples.

Here is code that shows what I want it to do:

The problem though, is that it's not that elegant since POSIXlt is outside
of read.zoo. Wondering if there's a way to put POSIXlt inside read.zoo and
compress things a bit to make the code run faster. Any ideas? Thanks.
Also, if there's any issues reading the file i uploaded to dropbox directly
off of the net with the code above, just use this:

Hope I covered everything in a compact reproducible manner. Sorry if I made
a noob mistake. Still kind of new.
