of the water-quality data must all agree, but numeric values are replicated to the
length of the water-quality data. See Details.
analyte
the name of the analyte, if not supplied, generated from ....
pcode
the parameter code of the analyte or any othe unique identifier the user chooses.
gt0
logical, if TRUE, then force values to be strictly non-negative on
