plot.windrose: Plot a wind rose diagram

Description

Plot a wind-rose diagram

Usage

## S3 method for class 'windrose':
plot(x, type=c("count","mean","median","fivenum"),
              convention=c("meteorological", "oceanographic"),
              mgp=getOption("oceMgp"), 
              mar=c(mgp[1], mgp[1], 1+mgp[1], mgp[1]), col, ...)

Arguments

x

a windrose object, e.g. as created by as.windrose.

type

the thing to be plotted, either the number of counts in the angle interval, the mean of the values in the interval, the median of the values, or a fivenum representation of the values.

convention

string indicating whether to use meteorological convention or oceanographic convention for the arrows that emanate from the centre of the rose. In meteorological convenction, an arrow emanates towards the right on the diagram if the

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").

col

an optional list of colours to use. If not set, the colours will be c("red", "pink", "blue", "lightgray"). For the first three types of plot, the first colour in this list is used to fill in the rose, the third is used for

...

optional arguments passed to plotting functions.

Details

Creates a wind-rose diagram.
