Multiply Water-Quality Data by a Number

Description

Multiplies water-quality data by a number while maintaining the integrity of the data.

Usage

multiply(x, factor, units, analyte, analyte.method = "ALGOR", pcode = "")

Arguments

`x`	an object of water-quality (class "qw"). Missing value are permitted and result in corresponding missing values in the output.
`factor`	a single numeric value
`units`	character reporting units of the resulting operation, if not supplied, retained from `x`.
`analyte`	character the name of the resulting analyte.
`analyte.method`	character the name of the analytical method for the result, by default "ALGOR."
`pcode`	the parameter code of the result, if not supplied, retained from `x`.

Details

Multiplication is not defined for objects of class "qw" because it can change some of the metadata, in particular the units, the analytical method, or the unique identifier (pcode).
