Coerce Something Into an Oce Object
an item containing data. This may be data frame, list, or an oce object.
An oce object.
This function is limited and not intended for common use.
In most circumstances, users should employ a function such
as.ctd() to construct specialized oce sub-classes.
as.oce creates an oce object from data contained within its
first argument, which may be a list, a data frame, or an object
of oce. (In the last case,
simply returned, without modification.)
x is a list containing items named
as.coastline() is called (with
the specified ... value) to create a coastline object.
x is a list created by
read_odf from the (as
yet unreleased) ODF package developed by the Bedford Institute of
ODF2oce() is called (with
no arguments other than the first) to calculate a return value.
If the sub-class inference made by
incorrect, users should call that function directly, specifying
a value for its
x has not been created by
read_odf, then the names
of the items it contains are examined, and used to try to infer
the proper return value. There
are only a few cases (although more may be added if there is
sufficient user demand). The cases are as follows.
