This function is used to isolate other oce functions from changes to the map-projection functions that are done in the sf package. (Until 2020 December, the rgdal package was used, after a year of tests ensuring that the results of the two packages were the same.)
oceProject(
xy,
proj,
inv = FALSE,
use_ob_tran,
legacy,
passNA,
debug = getOption("oceDebug")
)two-column numeric matrix specifying locations. If inv is False, then xy[,1] will hold
longitude and xy[,2] will hold latitude, but if inv is True, then the columns will be easting
and northing values (in metres).
character string indicating the desired map projection, or an object of class crs;
see sf::sf_project().
logical value, False by default, indicating whether an inverse projection is requested.
ignored in oce 1.0.3, and will be disallowed in oce 1.0.4.
an integer specifying whether debugging information is
to be printed during the processing. This is a general parameter that
is used by many oce functions. Generally, setting debug=0
turns off the printing, while higher values suggest that more information
be printed. If one function calls another, it usually reduces the value of
debug first, so that a user can often obtain deeper debugging
by specifying higher debug values.
A two-column matrix, with first column holding either
longitude or x, and second column holding either
latitude or y.
