Plot an image of a component of an amsr object.
an amsr object.
character value indicating the name of the band to plot; if not provided,
SST
is used; see the documentation for the amsr class for a list of bands.
optional numerical value giving the aspect ratio for plot. The
default value, NULL
, means to use an aspect ratio of 1 for world views,
and a value computed from ylim
, if the latter is specified in the
...
argument.
optional numeric vector of the z values for breaks in the color scheme.
If colormap
is provided, it takes precedence over breaks
and col
.
optional argument, either a vector of colors corresponding to the breaks, of length
1 less than the number of breaks, or a function specifying colors.
If neither col
or colormap
is provided, then col
defaults to
oceColorsTemperature()
.
If colormap
is provided, it takes precedence over breaks
and col
.
a specification of the colormap to use, as created
with colormap()
. If colormap
is NULL, which is the default, then
a colormap is created to cover the range of data values, using
oceColorsTemperature color scheme.
If colormap
is provided, it takes precedence over breaks
and col
.
See “Examples” for an example of using the "turbo" color scheme.
optional numeric vector of length 2, giving the limits of the plotted quantity. A reasonable default is computed, if this is not given.
optional list specifying colors to use for
non-data categories. If not provided, a default is used. For
type 1, that default is
list(land="papayaWhip", none="lightGray", bad="gray", rain="plum", ice="mediumVioletRed")
. For type 2, it is
list(coast="gray", land="papayaWhip", noObs="lightGray", seaIce="mediumVioletRed")
. Any colors may be used in place of these,
but the names must match, and all names must be present.
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.
extra arguments passed to imagep()
, e.g. to control
the view with xlim
(for longitude) and ylim
(for latitude).
In addition to fields named directly in the object, such as SSTDay
and
SSTNight
, it is also possible to plot computed fields, such as SST
,
which combines the day and night fields.
