Description

Plot directions data as polar plot.

Usage

plotDirections(
  azimuth,
  zenith,
  value,
  azimuthOffsetVal = 0,
  outerRadius = max(zenith) + max(zenith) * 0.01,
  zenithLabPch = 20,
  zenithLabCol = "darkgrey",
  zenithLabCex = 1,
  brks = seq(min(value), max(value), length.out = 10),
  cols = c("dark grey", colorRampPalette(c("purple", "blue3", "yellow",
    "red"))(length(brks) - 3), "firebrick4"),
  ...
)

Arguments

azimuth	Numeric. Azimuth angle with DART conventions
zenith	Numeric. Zenith angle with DART conventions
value	Numeric. Values associated with the given azimuth and zenith angles
azimuthOffsetVal	Numeric. Scene offset (degrees) as shown in the DART GUI.
outerRadius	Numeric. Maximum radius (degrees) of polar plot
zenithLabPch	Numeric. Pch for zenith label.
zenithLabCol	Character. Colour for zenith label.
zenithLabCex	Numeric. Cex for zenith label.
brks	Numeric. Breaks for colour palette e.g. seq(0, 1, by = 0.1). Optional.
cols	Character. Colours for given breaks. Optional.
...	Additional options passed to points() when drawing directions points.

Examples

#Inputs are DART oriented directions (as seen in the DART files and \link{Directions-class})
plotDirections(azimuth = rep(225, 10),
               zenith = seq(0, 90, length.out = 10),
               value = 1:10)
#Output plot uses 'upward' directions from ground, where e.g.:
  0deg (270deg) azimuth faces north (west)
  0deg (90deg) zenith faces upward (horizon)
