Windrose (speed/direction) diagram

Description

Plot a windrose showing the wind speed and direction using ggplot2.

Usage

ggwindrose(
  speed,
  direction,
  n_directions = 8,
  n_speeds = 5,
  speed_cuts = NA,
  col_pal = "GnBu",
  legend_title = "Wind speed (m/s)",
  calm_wind = 0,
  n_col = 1,
  facet = NULL,
  plot_title = "",
  ...
)

Arguments

speed	Numeric vector of wind speeds.
direction	Numeric vector of wind directions.
n_directions	Numeric value as the number of direction bins to plot (petals on the rose). The number of directions defaults to 8.
n_speeds	Numeric value as the number of equally spaced wind speed bins to plot. This is used if speed_cuts is NA (default 5).
speed_cuts	Numeric vector containing the cut points for the wind speed intervals, or NA (default).
col_pal	Character string indicating the name of the hcl.pals() color palette to be used for plotting.
legend_title	Character string to be used for the legend title.
calm_wind	Numeric value as the upper limit for wind speed that is considered calm (default 0).
n_col	The number of columns of plots (default 1).
facet	Character or factor vector of the facets used to plot the various windroses.
plot_title	Character string to be used for the plot title.
...	further arguments (ignored).

Value

A ggplot object.
