handleFlags {oce} | R Documentation |
Data-quality flags are stored in the metadata
slot of oce-class
objects in a
list
named flags
.
The present function (a generic that has specialized versions
for various data classes) provides a way to
manipulate the core data based on
the data-quality flags. For example, a common operation is to replace suspicious
or erroneous data with NA
.
If metadata$flags
in the object supplied as the first argument
is empty, then that object is returned, unaltered.
Otherwise, handleFlags
analyses the data-quality flags within
the object, in relation to the flags
argument, and interprets
the action
argument to select an action to be applied to matched
data.

An optional integer specifying the degree of debugging, with
value 0 meaning to skip debugging and 1 or higher meaning to print some
information about the arguments and the data. It is usually a good idea to set
this to 1 for initial work with a dataset, to see which flags are being
handled for each data item. If not supplied, this defaults to the value of

Each specialized variant of this function has its own defaults
for flags
and actions
