Marc,

   Do I even need to worry about these NAs? Thanks to Gabor I have a data
frame with 296 stream/parameter sets. Each set begins and ends on a
different date (used as the zoo index).

   What I want to do initially is plot the time series for each
stream/parameter to see what each has to tell us. In this case, if there are
years of NAs prior to the fist measurement for that stream/parameter pair,
will this affect anything.

   On a related note, I'm reading the zoo help pages and vignettes but do not
see the syntax for specifying which stream/parameter pair I want to plot.
What do I read to learn how to do this?
