Creates a multi-panel summary plot of data measured in a meteorological data
set. cast. The panels are controlled by the
a met object.
list of desired plot types.
which=1 gives a time-series plot of temperature
which=2 gives a time-series plot of pressure
which=3 gives a time-series plot of the x (eastward) component of velocity
which=4 gives a time-series plot of the y (northward) component of velocity
which=5 gives a time-series plot of speed
which=6 gives a time-series plot of direction (degrees clockwise from north;
note that the values returned by
met[["direction"]] must be multiplied by 10
to get the direction plotted)
A 3-element numerical vector used with
to control the spacing of axis elements. The default is tighter than the R default.
A 4-element numerical vector used with
to control the plot margins. The default is tighter than the R default.
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
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
If more than one panel is drawn, then on exit from
par will be reset to the value it had before the function
call. However, if only one panel is drawn, the adjustments to
plot.met are left in place, so that further additions may
be made to the plot.
Other functions that plot oce data:
