rgl.sphsun {sphereplot}

Plot ecliptic + Sun

Description

This function overplots the ecliptic plane on the default Equatorial coordinates, and optionally will add the Sun either for a desired date, or for today.

Usage

rgl.sphsun(Ydate = c(3, 21), radius = 1, col = "yellow", type = "s", sunrad = 0.02,
addeclip = TRUE, addsun=TRUE)

Arguments

Ydate

The date for the location of the Sun on the spherical grid. Vector in c(M,D) format. If set to 'get' then the function will return the Sun's location for today.

radius

The radius at which to draw the ecliptic plane and Sun.

col

The colour of the ecliptic line and for the Sun.

type

Rgl plot type for the Sun, default is to draw it as a 3D sphere, i.e. type 's'.

sunrad

The radius of the Sun if plotted as a sphere.

addeclip

Should the ecliptic plane be drawn.

addsun

Should the location of the Sun be plotted.

Value

No value, used for plotting side effect.
