This function creates an item for a named variable within
the flags entry in the object's metadata slot.
The purpose is both to document a flag scheme
and to make it so that initializeFlags()
and setFlags() can specify flags by
name, in addition to number. A generic function, it is
specialized for some classes via interpretation of the
scheme argument (see “Details”, for those
object classes that have such specializations).
initializeFlags(object, name = NULL, value = NULL, debug = 0)An oce object.
Character value indicating the name of a variable within the
data slot of object.
Numerical or character value to be stored in the newly-created
entry within flags. (A character value will only work if
initializeFlags() has been used first on object.)
Integer set to 0 for quiet action or to 1 for some debugging.
An object with the flags item within the
metadata slot set up as indicated.
If object already contains a flags entry with
the indicated name, then it is returned unaltered, and a warning
is issued.
