plotFrequency: Plot frequency data

Description

Plots joint probability of wind speeds and directions from a frequency object in a rose plot.

Usage

plotFrequency(freq, ...)

Arguments

freq

Frequency object created by frequency.

Optional graphical parameters, see below for details.

Optional graphical parameters

The following graphical parameters can optionally be added to customize the plot:

col: Vector of colours -- one colour for each wind speed bin or a single colour iffrequencyonly contains the total frequency per direction sector.
cex: Numeric value, giving the amount by which text on the plot should be scaled relative to the default (which is 1).

Examples

Run this code

# load and prepare data
data(winddata)
set40 <- createSet(height=40, v.avg=winddata[,2], dir.avg=winddata[,14])
set30 <- createSet(height=30, v.avg=winddata[,6], dir.avg=winddata[,16])
set20 <- createSet(height=20, v.avg=winddata[,10])
ts <- formatTS(winddata[,1])
neubuerg <- createMast(time.stamp=ts, loc=NULL, desc=NULL, 
	set40, set30, set20)
neubuerg <- clean(neubuerg)

# calculate frequency
neubuerg.freq <- frequency(neubuerg, 1)
neubuerg.freq.2 <- frequency(neubuerg, 1, bins=NULL)

# plot frequency
plotFrequency(neubuerg.freq)
plotFrequency(neubuerg.freq.2)

# customize plot
plotFrequency(neubuerg.freq, col=rainbow(5))
plotFrequency(neubuerg.freq.2, col=gray(0.4), cex=1.5)
