as.windrose {oce} | R Documentation |
Create a wind-rose object, typically for plotting with
plot,windrose-method
.
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. |
An object of windrose-class
that 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)
