Plot cm
(current meter) data
## S4 method for signature 'cm' plot(x, which=c(1:2, 7:9), type="l", adorn=NULL, drawTimeRange=getOption("oceDrawTimeRange"), drawZeroLine=FALSE, mgp=getOption("oceMgp"), mar=c(mgp[1]+1.5, mgp[1]+1.5, 1.5, 1.5), small=2000, main="", tformat, debug=getOption("oceDebug"), ...)
x |
an |

list of desired plot types. These are graphed in panels running
down from the top of the page. See “Details” for the meanings of
various values of |

adorn |
optional list of |
drawTimeRange |
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. |
drawZeroLine |
boolean that indicates whether to draw zero lines on velocities. |
mgp |
3-element numerical vector to use for |
mar |
value to be used with |
small |
an integer indicating the size of data set to be considered
"small", to be plotted with points or lines using the standard
|
main |
main title for plot, used just on the top panel, if there are several panels. |
tformat |
optional argument passed to |
debug |
a flag that turns on debugging. Set to 1 to get a moderate amount of debugging information, or to 2 to get more. |
... |
optional arguments passed to plotting functions. |
Creates a multi-panel summary plot of data measured by a
current meter. The panels are controlled by the which
argument, as follows.
which=1
or which="u"
for a time-series graph of eastward
velocity, u
, as a function of time.
which=2
or which="v"
for a time-series graph of
northward velocity, u
, as a function of time.
which=3
or "progressive vector"
for progressive-vector
plot
which=4
or "uv"
for a plot of v
versus u
.
(Dots are used for small datasets, and smoothScatter for large ones.)
which=5
or "uv+ellipse"
as the "uv"
case, but
with an added indication of the tidal ellipse, calculated from the eigen
vectors of the covariance matrix.
which=6
or "uv+ellipse+arrow"
as the "uv+ellipse"
case, but with an added arrow indicating the mean current.
which=7
or "pressure"
for pressure
which=8
or "salinity"
for salinity
which=9
or "temperature"
for temperature
which=10
or "TS"
for a TS diagram
which=11
or "conductivity"
for conductivity
which=20
or "heading"
for compass heading
