radial.grid: Display a radial grid

Description

radial.grid displays a radial grid for the radial.plot and radial.pie functions.

Usage

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)

Arguments

labels

The labels to display around the circumference of the grid.

label.pos

Radial positions for the labels.

radlab

Whether to rotate the labels to a radial orientation.

radial.lim

Optional radial limits for the circular plot. If specified, these must be the same as the radial limits of the original plot.

start

The zero position on the plot in the units of label.pos.

clockwise

Whether to increase angles clockwise rather than the default counterclockwise.

label.prop

Proportion of radial.lim to place the labels.

grid.pos

Radial positions for the circular grid lines.

rad.col

Color for the radial grid lines.

grid.col

Color for the circumferential grid lines.

grid.bg

Background color for the radial grid.

show.radial.grid

Whether to display the radial lines on the grid.

start.plot

If TRUE, sets up a blank radial grid.

Value

nil
