Is there a way to omit only those rows where all columns contain 'NA'?
You can look at ?complete.cases for one approach, presuming that it will work on zoo objects.
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?
