Hi,

I am new to R and looking to do auto-regression / ARIMA type modeling.  My
data has both date and time which I need to combine into a single date-Time
value.  The time steps are unequal.  What package is best for doing the
regression and plotting the predicted values against the actual data?
 Also, what format does my data need to be in when I use the package?  For
example, I looked at the cts package documentation and it has examples for
data(V22174) *but I have no idea how the data in V22174 looks*.  Is it a ts
object, a zoo object ... etc?  Lastly, if I have two different measurements
for the time series data (e.g., heading and displacement) can I do a
multivariate regression?

Thank you,
Keith
