as.windrose {oce} | R Documentation |
Create a wind-rose object, typically for plotting with plot.windrose().
as.windrose(x, y, dtheta = 15, debug=getOption("oceDebug"))
x |
the x component of wind speed (or stress) or an object of
class |
y |
the y component of wind speed (or stress). |
dtheta |
the angle increment (in degrees) within which to classify the data |
debug |
a flag that turns on debugging. Set to 1 to get a moderate amount of debugging information, or to 2 to get more. |
This is analagous to a histogram, but with breaks being angles.
An object of class
"windrose"
,
which contains the standard oce
slots named data
, metadata
and
proxessingLog
. The data
slot contains
n
the number of x values
x.mean
the mean of the x values
y.mean
the mean of the y values
theta
the central angle (in degrees) for the class
count
the number of observations in this class
mean
the mean of the observations in this class
fivenum
the fivenum
vector for
observations in this class (the min, the lower hinge, the
median, the upper hinge, and the max)

Use plot.windrose
to produce a summary plot, and
summary.windrose
to produce a numerical summary.
