radial.grid displays a radial grid for the radial.plot and radial.pie functions.
radial.grid(labels=NA,label.pos=NULL,radlab=FALSE,radial.lim=NULL,
start=0,clockwise=FALSE,label.prop=1.1,grid.pos=seq(0.25,1,0.25),
rad.col="gray",grid.col="gray",grid.bg="transparent",show.radial.grid=TRUE,
start.plot=FALSE)nil
The labels to display around the circumference of the grid.
Radial positions for the labels.
Whether to rotate the labels to a radial orientation.
Optional radial limits for the circular plot. If specified, these must be the same as the radial limits of the original plot.
The zero position on the plot in the units of label.pos.
Whether to increase angles clockwise rather than the default counterclockwise.
Proportion of radial.lim to place the labels.
Radial positions for the circular grid lines.
Color for the radial grid lines.
Color for the circumferential grid lines.
Background color for the radial grid.
Whether to display the radial lines on the grid.
If TRUE, sets up a blank radial grid.
