zoo, zooreg, & ISOdatetime
I create a zooreg object that runs from Jan-1-2002 0:00 to Jun-1-2005
0:00...
regts.start = ISOdatetime(2002, 1, 1, hour=0, min=0, sec=0, tz="")
regts.end = ISOdatetime(2005, 6, 1, hour=0, min=0, sec=0, tz="")
regts.zoo <- zooreg( NA, regts.start, regts.end, deltat=3600 )
Upon inspection:
> regts.zoo[1:3]

Timeseries Data Plotted as Monthly Boxplots
Hello, I'm trying to develop a box plot of time series data to look at the
range in the data values over the entire period of record.
My data initially starts out as a list of hourly data, and then I've been
using this code to make this data into the final ts array.
# Read in the station list
stn.list <- read.csv("/home/kbennett/fews/stnlist3", as.is=T, header=F)
# Read in

ARIMA (seasonal) backcasting & interpolation
Thanks for everyone's help with zoo -- I think I've got my data set
ready. (The data consists of surface weather temperatures, from 2002
to 2005, one observation per hour. Some values are missing... i.e. NA)
I have three goals:
GOAL #1:Get the data in proper time series form, preserving frequency
information:
> w4.ts <- as.ts( w3.zoo, frequency=(1/3600) )
I hope that 1/3600

problem with asterisk AGI
I have a fairly complicated setup. Extensions (1,2 and 3). In 3 - I
execute AGI in java which plays few wav files depending on external
parameters.
Can I have a dial plan inside my AGI? If not, how do I accomodate user
who needs to reach extension 2 from my agi? I have tried stream file and
get data but the two commands did not work at all.
