sep = "\t", aggregate = function(x) tail(x, 1))

read.zoo - combining two columns with date and time respectively into one index column?
I have three columns in my raw data: date, time, and dry bulb temperature:
http://r.789695.n4.nabble.com/file/n4495326/weathDataSDCoron.txt
weathDataSDCoron.txt
The date format is %Y%m%d and the time format is %H:%M. Any ideas on how to
read it in such that it looks at the first two columns and then merges it
into one column combining both the date and time?

Wrong output due to what I think might be a data type issue (zoo read in problem)
Here's the small scale version of the R script:

Here's the file that I'm reading in:
http://r.789695.n4.nabble.com/file/n4487682/weatherData.txt weatherData.txt
I apologize for the length of the data. I tried to cut it down to 12 lines,
however, it wasn't reproducing the bad output that I wanted to show.
The problem is that my whole data set

convert zoo object to "standard" R object so I can plot and output to csv file
Another newbie question
I got the 1 minute spine interpolation and 15 mean aggregation working with
many thanks to Gabor Grothendieck using Zoo functions. I got a tip from
Hasan Diwan to look at xts but it seemed I would make better progress using
code from Gabor.
Now I'm having trouble plotting this zoo object. I'm thinking I want a
function to "split" the zoo object back to
