Deprecated and Defunct Elements of package ‘oce’


Certain functions and function arguments are still provided for compatibility with older versions of ‘oce’, but will be removed soon. The ‘oce’ scheme for removing functions is similar to that used by ‘Bioconductor’: items are marked as "deprecated" in one release, as "defunct" in the next, and then removed entirely. This goal is to provide a gentle migration path for users who keep their packages reasonably up-to-date.


Several ‘oce’ functions are marked "deprecated" in the present release of oce. Please use the replacement functions as listed below.

Deprecated Replacement Notes
mapZones mapGrid Improve name sensibility
mapMeridians mapGrid Improve name sensibility

The next CRAN release of ‘oce’ will have these functions flagged as "defunct", which will mean that trying to use them will generate an error and a hint as to the replacement function.

The following are marked "defunct", which means that calling them in the present version of oce will produce an error, and that they will be removed altogether in the next oce release on CRAN.

Several ‘oce’ function arguments are considered defunct but are being permitted in the present CRAN release. They are as follows.

  • The date argument of as.ctd was discovered to have been unused in early 2016. Since the startTime actually fills its role, date was considered to be deprecated in June 2016.

  • The quality flag of as.ctd was marked as deprecated in March 2016.

  • The fill argument of mapPlot was confusing to users, so it was designated as deprecated in June 2016. (The confusion stemmed from subtle differences between plot and polygon, and the problem is that mapPlot can use either of these functions, according to whether coastlines are to be filled.) The functionality is preserved, in the col argument.

  • The adorn argument of plot,ctd-method and other functions was realized in June 2016 to be dangerous. (If the adornment code contained assignments to temporary variables, there could be conflicts with the plotting code. The only way to be sure of not overriding an important variable would be to understand the full plotting code, which is far too demanding to justify.) The solution is for users to draw panels individually, adding graphical elements with conventional R functions such as lines, etc.
