Does anyone know why this is happening?
> diff.prop[1:5]
         1          2          3          4          5 
-0.6323988 -0.5226586 -0.5605096 -0.6656347 -0.6011561 
> ts(diff.prop, start = c(1997, 11), frequency = 1)
Time Series:
Start = 2007 
End = 2125 
Frequency = 1 
[snip]

diff.prop is a vector, I want to convert it to a time series starting from Nov 1997 on a monthly basis.  However when it's created it starts from 2007.  It's happening on both R 1.8.1 and R 1.9.0 on Windows XP Pro

Cheers,

Kevin
