times in the top-left margin.expression or vector of expressions that contain
R code that is to be executed immediately after each panel of the plot.
If the number of expressions matches the number of panels, then the
expressions are used for the corresponding panels; otherwise, the
expression list is extended to match the number of panels (i.e.
to obtain length(which) elements). Note that adorn
is a dangerous argument, because if the expressions contained
therein set up local storage, there is a chance of entirely
disrupting the plotting. For this reason, adorn was
marked as defunct in June 2016, and will be removed entirely
after the July CRAN release. Users with existing code that uses
adorn should simply plot the panels individually, and
use conventional R functions, e.g. lines etc.,
after each panel, to achieve the desired effect. (See
oce-defunct for notes on other deprecated or
defunct oce features.)TRUE to fill the curve to zero (which it
does incorrectly if there are missing values in y).par("xaxs").par("yaxs").par("cex").par("cex.axis").par("cex.main").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.par("mar") to set margins.
THe default value uses significantly tighter margins than is the norm in R,
which gives more space for the data. However, in doing this, the existing
par("mar") value is ignored, which contradicts values that may have
been set by a previous call to drawPalette. To get plot with
a palette, first call drawPalette, then call
oce.plot.ts with mar=par("mar").despike.TRUE to get axes plottedimagep.TRUE, a grid will be drawn for each panel. (This
argument is needed, because calling grid after doing a
sequence of plots will not result in useful results for the individual
panels.plot.xat and yat,
values that can be used by oce.grid to add a grid to the plot.
plot and
plot.ts routines will not obey the time zone of the data.
This routine gets around that problem. It can also plot the time range in
the top-left margin, if desired; this string includes the timezone, to
remove any possible confusion.
The time axis is drawn with oce.axis.POSIXct.
