Plot pT temperature-depth recorder data
## S3 method for class 'pt': plot(x, which=1:4, title=deparse(substitute(x)), adorn=NULL, tlim, plim, Tlim, xlab, ylab, draw.time.range=getOption("oce.draw.time.range"), mgp=getOption("oce.mgp"), mar=c(mgp[1], mgp[1]+1, 1, 1.5), ...)
x |
pt object, typically result of read.pt . |
which |
if a subset of the plots is required, specify a subset of the numbers 1:4. These are codes for the panels, which will be drawn from top-left to bottom-right (see Details). |
title |
character string to be used in the text-summary panel
(which =2) |
adorn |
list of expressions to be executed for the panels in turn, e.g. to adorn the plots. If the number matches the number of panels, then the strings are applied to the appropriate panels, as they are drawn from top-left to bottom-right. If only a single expression is provided, it is used for all panels. (See “Examples”.) |
tlim |
optional limits for time axis. If not provided, the value will be inferred from the data. |
plim |
optional limits for pressure axis. If not provided, the value will be inferred from the data. (It is helpful to specify this, if the auto-scaled value will be inappropriate, e.g. if more lines are to be added later.) |
Tlim |
optional limits for temperature axis. If not provided, the value will be inferred from the data. (It is helpful to specify this, if the auto-scaled value will be inappropriate, e.g. if more lines are to be added later.) |
xlab |
optional label for x axis. |
ylab |
optional label for y axis. |
draw.time.range |
boolean that applies to panels with time as the horizontal axis, indicating whether to draw the time range in the top-left margin of the plot. |
mgp |
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. |
mar |
value to be used with par("mar") . |
... |
optional arguments passed to plotting functions. |
Several plots are available: which
=1 for a timeseries
plot of temperature,
which
=2 for textual information about the dataset,
which
=3 for a timeseries plot of pressure,
and
which
=4 for a scatterplot of the temperature profile, . You
may supply a list of which
values, to get multi-panel plots.
