Description

Plots wind speeds against directions in a polar plot.

Usage

plotPolar(mast, v.set=1, dir.set=1, ...)

Arguments

mast

Met mast object created by createMast.

v.set

Set used for wind speed values as integer value.

dir.set

Set used for wind speed values as integer value.

Optional graphical parameters

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

• col: The colour of the symbols plotted.
• pch: Either an integer specifying a symbol or a single character to be used as symbol -- seepointsfor possible values and their interpretation.
• cex: Numeric value, giving the amount by which text on the plot should be scaled relative to the default (which is 1).
• cex.pts: Numeric value, giving the amount by which the plot symbols should be scaled relative to the default (which is 1).
