R help - Sep 2008 - dealing with NAs in time series

Certain timeseries I have had outliers, which I removed by assigning  
NA to their positions.  Now acf() refuses to go to work.  What's the  
right way to remove outliers from ts objects, and what are teh  
standard ways to interpolate NAs in them?

Cheers,
Alexy

look at zoo
na.approx
this will interpolate in a couple of ways

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods. We are mammals, and have not exhausted the
annoying little problems of being mammals.
