polar.plot {plotrix} | R Documentation |
polar.plot displays a plot of radial lines, symbols or a polygon centered at the midpoint of the plot frame on a 0:360 circle. Positions are interpreted as beginning at the right and moving counterclockwise unless start specifies another starting point or clockwise is TRUE.
polar.plot(lengths,polar.pos=NULL,labels,label.pos=NULL, start=0,clockwise=FALSE,rp.type="r",...)
lengths |
numeric data vector. Magnitudes will be represented as the radial positions of symbols, line ends or polygon vertices. |
polar.pos |
numeric vector of positions on a 0:360 degree circle. These will be converted to radians when passed to radial.plot. |
labels |
text labels to place on the periphery of the circle. This defaults to labels every 20 degrees. For no labels, pass an empty string. |
label.pos |
positions of the peripheral labels in degrees |
start |
The position for zero degrees on the plot in degrees. |
clockwise |
Whether to increase angles clockwise rather than the default counterclockwise. |
rp.type |
Whether to plot radial lines, symbols or a polygon. |
... |
additional arguments passed to radial.plot and then to plot. |
