R help - Jun 2007 - use ts objects within the "seas" package for seasonal stats ; to compare years with each other for change detection

Hi all,

 

Does anyone know how ts objects ts(base) can be used within the 'seas'
package? I would like to obtain seasonal statistics of regular
time-series and for example look at the result of the plot.seas.var()
function or use the change function() to look at change between periods
or time-series.

 

The nottem time-series are similar to the time-series we are analyzing
(but with data frequency=46 instead of 12 of the nottem dataset).  We
have year and day of year available but not the date (-> is there a
function to derive a date format such as e.g. 01-01-2007 from day 1,
year 2007?)

nottem

plot(nottem)

 

 

I couldn't find anything about this on the R discussion - or www. 

 

Thanks and cheers,

Jan
