This plots contours of topographic elevation. The plot aspect ratio is set
based on the middle latitude in the plot. The line properties, such as
land.lwd, may either be a single item, or a vector; in the latter case,
the length must match the length of the corresponding properties, e.g.
land.z.

)a topo object.
Character strings giving a label for the x and y axes.
Aspect ratio for plot. The default is for plot.coastline to
set the aspect ratio to give natural latitude-longitude scaling somewhere near
the centre latitude on the plot. Often, it makes sense to set asp
yourself, e.g. to get correct shapes at 45N, use asp=1/cos(45*pi/180).
Note that the land mass is not symmetric about the equator, so to get good
world views you should set asp=1 or set ylim to be symmetric
about zero. Any given value of asp is ignored, if clongitude and
clatitude are given.
Optional center longitude of map, in degrees east; see
clatitude.
Optional center latitude of map, in degrees north. If this
and clongitude are provided, then any provided value of asp is
ignored, and instead the plot aspect ratio is computed based on the center
latitude. Also, if clongitude and clatitude are provided, then
span must be, also.
Optional suggested span of plot, in kilometers (must be supplied,
if clongitude and clatitude are supplied).
Numerical factor for the expansion of plot limits, showing area
outside the plot, e.g. if showing a ship track as a coastline, and then an
actual coastline to show the ocean boundary. The value of expand is
ignored if either xlim or ylim is given.
Depths at which to plot water contours. If not provided, these are inferred from the data.
Colors corresponding to water.z values. If not
provided, these will be "fill" colors from
oce.colorsGebco().
Line type(s) for water contours.
Line width(s) for water contours.
Depths at which to plot land contours. If not provided, these
are inferred from the data. If set to NULL, no land contours will be
plotted.
Colors corresponding to land.z values. If not
provided, these will be "fill" colors from
oce.colorsGebco().
Line type(s) for land contours.
Line width(s) for land contours.
Logical, indicating whether to plot latitudes and longitudes without minus signs.
Location for a legend (or "none", for no legend).
3-element numerical vector to use for par(mgp), and also for
par(mar), computed from this. The default is tighter than the R
default, in order to use more space for the data and less for the axes.
Four-element numerical vector to be used with
par("mar").
Numerical value, with positive values indicating higher levels of debugging.
Additional arguments passed on to plotting functions.
