<dd><p>A list specifying flag values upon which actions will be taken. This can take two forms.</p>
<p>In the first form, the list has named elements each containing a vector of
integers. For example, salinities flagged with values of 1 or 3:9 would be
specified by flags=list(salinity=c(1,3:9)). Several data items can be
specified, e.g. flags=list(salinity=c(1,3:9), temperature=c(1,3:9)) indicates
that the actions are to take place for both salinity and temperature.<
