as.windrose: Create a windrose object

Description

Create a wind-rose object, typically for plotting with plot.windrose().

Usage

as.windrose(x, y, dtheta = 15, debug=getOption("oceDebug"))

Arguments

x

the x component of wind speed (or stress) or an object of class met (see met-class), in which case the u and v components of that object are use

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.

Value

• An object of class "windrose", which contains the standard oce slots named data, metadata and proxessingLog. The data slot contains [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Details

This is analagous to a histogram, but with breaks being angles.
