rgl.sphgrid: Create a spherical plotting grid

In asgr/sphereplot: Spherical Plotting

Create a spherical plotting grid

Description

Creates a spherical plotting grid, within which further points can be added. Useful for astronomical plotting in particular, where this becomes the celestial sphere.

Usage

rgl.sphgrid(radius = 1, axis.val = TRUE, col.long = 'red', col.lat = 'blue',
  col.rad = 'darkgreen', col.axes = 'grey50', col.grid = 'grey', deggap = 15,
  longtype = "H", add = FALSE, radaxis = TRUE, radlab = 'Radius', col.radlab = 'black')

Arguments

radius	The radial extent of the spherical grid.
axis.val	Logical; show numeric values on the spherical grid.
deggap	The attempted separation between sherical grid lines in degrees.
col.long	The colour for longitude axis value labels.
col.lat	The colour for latitude axis value labels.
col.rad	The colour for radius axis value labels.
col.axes	The colour for axes (i.e. grid line next to labels).
col.grid	The colour for grid lines.
longtype	Specifies if longitudes should be labelled in hours (H- default) or degrees (D).
add	Should the grid be added to the current plot, or if FALSE a new rgl device is launched.
radaxis	Logical determining whether the sphere radius vector is drawn and labeled (default is TRUE). Pretty labeling is used to choose the location of ticks and labels.
radlab	If 'radaxis' is TRUE then the 'radlab' parameter determines the name of the label.
col.radlab	Colour of the radius title.

Details

This function should be called first, and can generally be used with only the declaration of radius to good effect.

Value

No value, used for plotting side effect.
