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

x is a list created by
read_odf from the (as

ODF2oce() is called (with
no arguments other than the first) to calculate a return value.
If the sub-class inference made by

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.
x contains items named
